KEV YOU HAVE NO IDEA ON HOW MANY PEOPLE YOU HAVE INSPIRED OVER THE YEARS YOU'VE BEEN ON UA-cam. IM ONE OF THEM. WE ALL LOVE YOU TERESA AND LISA. YOU ARE AWESOME 😊
Streetips thank you for the time you take to explain the process, and don’t be discouraged by those few thumbs down, thumbs down are the people who wants to learn the process but, they never liked schools, the minute they see that mathematics is the key to get ahead on this trade, they give you a thumbs down. But it’s a good thing that they see the chemical reaction between the acids and the heat, and they will never dear to do the process by themselves and injure themselves or even get killed.
Kwinzman using f instead of c is totally fine for a lot of the world. Believe it or not some of us still drive on the right side of the road not the left.
Making my way thought your older content and I gotta say, I could watch you sort through old jewelry for hours. Something about it is so interesting and soothing.
I’d say it’s in our DNA gold/silver money ie real money since the beginning they psychologically also use the current currency coinage ie the 50p pence is silver in look same as the 5p and 20p then we have the £1 & £2 coin both on appearance the £1 & £2 coin looks to be gold and silver that’s the institutional nod to their knowledge on real currency and what it really should be but they instead give us none precious metals masquerading as precious by look only and back by confidence only 😂👍🏻
Another awesome video. I feel like I just ran a marathon and all I did was watch. I can't imagine how you must have felt doing the work. Thank you for your efforts!
This is probably one of your best training videos I've seen!! You said at the end of the vid that it was hard to video this one, but I didn't see it!! It looked real smooth from my view!!! Have a GREAT Day My Friend!!!!
Your attention to detail is amazing! When you have misspoke, you or your editor always corrects it with captions, even though anyone who's watched more than a dozen of your vids knows what you meant to say! There are those that need it, the 1st time watchers and those that just don't pay attention. I have what might be a rhetorical question, because I believe I know the answer. When you put ice in to cool the gold precipitate (just before filtering) I'm assuming that's plain tap water. Because one of the main reasons you use distilled is to prevent silver chloride, but at that point of adding ice you know there's no possibility of silver in solution, therefore no need for distilled. Is this way of thinking correct?? So many things to say about this excellent video!!! This question is one that I've thought about, but don't ask because I think it sounds like a foolish question!!! Thank you, Sreetips!!!
The master does it again, I for one want to say thank you Sreetips, you have spawned a Generation of refiners, not including myself, Cheers, and keep up the good work!
YES !!!!!! Other then watching the discovery channel, when they did the "GOLD" show, this is the biggest pour I have ever had the privilege of watching. I appreciate your shows when you call out that ((Todays topic was not a venture to make money, rather, to explain the process and the math behind it, and that your methods work)), but, Yes, I know, you are putting in the leg work already, but, to hear some numbers, as to an abstract price, for what you have invested, into chemical(s) usage VS. the out come in the precious metals. I wouldn't dare hold you accountable, to state the facts, as costs fluctuate every minute, but, an abstract/approximate cost, to profit ratio would be so satisfying to hear. I have approx. 650 lbs of gold and silver crap from mil spec surplus, to just plated E-scrap junk. After 17 years of collecting the crap, I am still not confident enough to just jump into handling this whole processes, due to the dangers, that are typically safe for a person who knows fully what they are doing, and knows how to handle the bi-products. Until I get to the point that I fully understand the game, I am too chicken, LOL... The likeliness that it will be another 17 years, before I jump into this, I may resort to just trying to sell the stuff as it is, and let a company that does this stuff every day, deal with it. I have to mention, the past years, I am so interested in chemistry, but, I still feel like I am missing so much, or to say, "the more I learn, the more questions pop up"... This stuff is so neat, Keep up the fine work, Sir, I have learned quite a bit, that even the few books, never covered, and are logical, as to why or when you have done a procedure. Thank you, Dru
Dru, you would do better selling it on eBay. On the other hand, if you are interested in learning how to refine your material then just having it to work with is priceless. I don't process much escrap because the yields are too low and the amount of waste is usually high.
This is the best practical demonstration of these skills I have seen on the internet. Your site will be treasured like my copy of Recovery and refining of Precious metals by C.W. Ammen.
I'm glad to see I'm not the only one who has marathon sessions while making videos for their channel :) I had just such a one a couple of days ago, and I got to bed at only 8am the next morning. Let's hope our viewers will like what we did... the only thing is, I still need to edit my video while yours is already out there! Nice video by the way, I'm always entertained watching them... now, please excuse me, I have a video to edit :)
That was an awesome video. I think that time and effort paid off because the weight of the gold is worth over $5600. Not too bad for a couple day's work.
Never fail to learn something from Mr Sreetips. I'm literally confident with movinh forward with recovering ans refining Silver from Sterling. I'm really wanting to know more about like fume hoods, glassware and containers uses for processing. I see you run through so much Nitric and it makes my wallet hurt. Actually surprisingly simple to make but for someone who can afford the Nitric Acid it's a non-thought.
@sreetips that's a fair but not obscene amount at all when your hobby or business needs it. Now from my immediate thoughts of wanting to recover silver from Sterling is can I make a profit after selling the silver? If I had the means at the moment to refine gold, that wouldn't even be a question.
I just discovered your channel today and I am very intrigued. I love stuff like this. Because of you I am more intriguged than ever To learn how to do this. I know it will take time, but if I am able to do what you did Eventually with jewelry that my family no longer wants or sterling silver my family no longer wants I could make them a pretty penny. Who needs Cash for Gold services when you could make more money doing it yourself, even factoring in the chemicals, electricity, patience (thank God for my ADHD lol) etc. needed to produce the gold. God I love chemistry.
Paul, I just wish videos like these were around when I first started about 8 years ago. Back then there was nothing. No books, no magazines. I did stumble on the goldrefiningforum.com and that's where I learned how to do it.
Now all that knowledge is spinning in me head !, I know when I go do my gold I'am going to have to watch this in parts To bad on your mold Yet a beautiful bar of gold !, Thanks for sharing Enjoyed
Hello Mrs and Mr Sreetips..So good memories. So nice to see how you take us subscribers in the passion for gold refining. I hope it soon come some sponsorship people to provide this chanal. So you can produce clip that you dream about Mr Sreetips. It is a blessing to see more and more subscribers hit that button. This clip is a highlight 🌷🌷 I know you and your wife is so humble. For me have all you clips realy been a blessing in good and bad days. God bless you more and more🌷🌷See forward to guitar intro's. I am playing guitar my self. Country and blues offcourse. Have s wonderful evening and night both of you. So nice to be a part of the Sreetips family. Thank you so muth 🌷🌷🌷 Arne
This video is worth about as much as the amount of gold you yielded in the video. I don't know how you can afford what it must cost to pay for the positive comments these "people" are leaving. There can't be that much plated gold out there.
Gold is everywhere. But in such small quantities that it’s not worth trying to get it. I didn’t know you could pay people for positive comments. Always thought that you had to earn them.
It was a good video. Both parts were done very well . I was just a little let down to find out at the end that I wouldn't get rich. I let it get the best of me. Wow Joe Rogan even commented.
You are awesome. This video is your best in my opinion. Could you please make a video focused completely on the math and where and why you get the numbers?
You know what I just thought about something he was to tell me openly on here where you buy your gold and silver you with this many followers they would all be buying a the supplies that you use so they don't worry about it I will find it places to get it on my own thank you very much!
If you add silica sand to the gold melt with a bit of borax and just let it cool after melt, you can pull the hardened wad out of the crucible and whack it to break the glass and trash metal off the gold. The silica sand forms a barrier between the gold and trash. The borax helps to separate them.
Kevin, melting the metals, with borax, sand, or any other compound, will cause the metals to alloy. Some junk may be removed by fluxing like this, but it will not separate other metals from the gold. The only way to get three nines gold is to refine it with a wet chemical process.
Really cool video. Where do you get all of the jewelry that you refine? You mentioned yard sales and flea markets? How does a guy like me that has no real knowledge of what to look for at these sales get into buying gold/silver jewelry to make a little profit? I mean I can just take a test stone/acid to a yard sale to test everything. Thanks.
The is no substitute for experience. I can tell just by looking if a piece is gold or silver. Because ive been doing it now for about 15 years. We go to yardsales every weekend. Here's an inside tip: take a small magnet with you. If the piece your interested in sticks to it, then it's probably not a precious metal. The magnet will stick to iron (and nickel) and precious metals are not normally alloyed with iron. A magnet is a gold buyers best friend. But if it don't stick it doesn't mean that it's gold. It could be gold plated over copper or brass, neither will stick to a magnet.
I've had to break them before because too much borax in with the gold. I calculate 91+36+2 grams of pure gold. And I got 135 grams. There may have been some extra gold over the silver items that I added. And I added 5 grams of pure gold during the inquartation so that may have thrown things off a bit.
Just watched this all last evening. Very interesting. I've just subscribed. Two questions that you may address elsewhere. 1. Does this all need to be done in one sitting or can it be left overnight and picked up? 2. Are chemicals the only way to do this or is there a less caustic way to extract gold?
Hi Streetips tbo you make the best refining & recycling videos on UA-cam I have a question on AP solution. I used the AP to scrap some motherboards my solution was dark green after that I took some scrap stainless steel and put it into the solution to pull the copper out. Now my solution is blue. What does that mean what kind of metal is still in the solution? Can I recover that metal? Thank you for your time, I know it's the
MrErikm stainless has other metals in it chromium nickle aluminum and others I use a good ol piece of iron to drop copper from solutions leaves for cleaner waste yours now has thoes other metals in it making it just as nasty as before I'm not sure how to recover these other base metals others hopefully will add to help u fix it good luck ...
@@sreetips Ah isee noted. that means because in this video after the first aqua regia you deem the gold was not cleaned enough hence you thought it was necessary to do it second time in order to get a cleaner one at the end. thanks for the answer! appreciate it.
Sir, you listed an "in-depth" formula recommended by a viewer in a previous video. I have forgotten which it was! Could you refresh my memory which one it was? Thanks!
Fantastic video. I am getting real close to trying my first attempt. The one thing I have a problem with are the fumes. Ok, they go up the flue but them where? I can’t afford a professional scrubber. I just don’t want to harm the dogs if they are walking around my shop. Do the fumes dilute to a safe level once They are sucked outside? Thanks and a wonderful video.
The fumes can cause serve distress several weeks after exposure. Frequent exposure in large amounts can kill. Keep the fumes away from people and pets.
brilliant video best ive seen. when you pour the aqua reqis through the filter doesnt that disolve the filter and the smb used for recovery. can that just be washed off as it always stays as a white powder at the bottom of my jar
the filter will not dissolve. But it will disintegrate in hot aqua regia. SMB is soluble in water. It can be rinse from the precipitated gold powder easily with water. But I have melted gold powder in the filter that is sopping wet with SMB. It doesn't hurt the purity of the gold.
I use a lab grade filter paper that I purchased on eBay. Number two or medium flow. Silver chloride is slightly soluble in the chloroauric acid solution. If the solution is hot then the chloride will stay in solution and pass right through the filter. But it is less soluble if the solution is cold. After adding ice (or by adding cold water) the silver chloride will come out of solution and the solution will turn cloudy. Then some of it can be filtered out. This is the main reason for cooling the solution.
loved that video mate, the length was good too. is it just my end or have the last 2 videos been much much quieter i can hardly hear you at your desk at all
You are a pretty good chemist. The only think I don’t agree on it ever using tap water, I know sometimes it don’t hurt but I feel if you use to different waters you may not be thinking good accidentally put tap water when you should put distilled water. That’s just me.
I'm not a chemist. I do this as a hobby. After refining thousands of ounces of silver and hundreds of ounces of gold, knowing when to use tap water and when to use distilled water just kind of comes naturally. I've never accidentally poured tap water into a silver nitrate solution. Not yet anyway.
You add sulfuric acid to precipitate lead (if there is any). Does any jewelry typically contain lead, or are you concerned about lead that may have been in solder?
Thank you for your videos! They are very detailed and explanatory. I enjoyed every single second of every video that I have watched so far on your channel. Could you please tell me the concentration of the first nitric acid you're using for the inquarted alloy and the concentration of the con nitric acid you've used for the aqua regia treatment? And also, it would help a lot if you could mention these concentrations in your next videos as I am sure some of us use your videos as a step by step guide for the process. Many thanks and keep up doing these brilliant videos
Someone said in a previous comment that "you may have spawned a new generation of refiners" and he might be 100% right. Personally I didn't know I could enjoy this so much until I accidentally found one of your videos, and then it hit me
I'll have to say you do awesome work. You should get your name out there using Facebook becoming a member to some of those gold prospecting groups there's a lot of them
I’m not a chemist. I couldn’t explain it because I don’t know how. You don’t have to be a chemist to refine gold and silver. Platinum is a whole different story.
I know this videos two years old but I have a question where do you purchase your scrap gold and silver? Thank you in advance for telling me I really enjoy your videos!
Sreetips, great vid. Question regarding breaking the mold (as someone who hates wasting stuff as I am sure you are): could you have hit the gold with the torch for a while to melt the flux and a bit of the gold, then dumped out of the mold?
You use a gas flame above the melting temperature of gold. Is the weight of the dry gold any different after you melt it? Do you lose any gold? I see the golden dirt compresses into a solid. Is there a weight loss? Thank you. Is the extra heat used to evaporate the impurities? I bought an electric 3K furnace to see it is can improve on the process. Gas is quicker I think. It takes 45 minutes to melt .5 kg of gold in an electric furnace.
Mike, in these placer gold videos I was searching for a way to extract the pure gold without having to use any nitric acid. But my preferred method would be to inquart the placer with silver and then part with hot dilute nitric acid. Inquarting and part with hot dilute nitric gets all the impurities out. Then I can usually get pure gold with the first aqua regia refining. Thank you!
How would you recommend to refine gold in form of very thin flakes from industry scrap? Its beyond paper thin but a lot of leefs, like 1kg. What aboit meltimg it down in a furnace first to het some bigger nuggets?
I have one question. so your total yield ended up being about 5 grams more than the calculated amount of pure gold for each karate, is this because some of the jewelry melted most likely contained more gold than the stated karate? PS these videos are so great and informative. Thank you.
Very unlikely. Most karat gold is under, not over, in the amount of gold it contains. I probably tossed some higher karat gold in to a low karat bin because the marking was rubbed off.
I love your videos and great information as always. Have you ever calculated the cost of your materials (electricity, acids, smb, etc...) for purifying the gold, silver, and copper per gram? Just wandering the profit from purifying.
The silver and copper solution: I get the silver one of two ways, either add clean pieces of copper to the blue solution to "cement" the silver out of solution, or add hydrochloric acid and precipitate pure silver chloride, then convert the silver chloride to pure silver metal with lye and sugar. The copper, not being a precious metal, gets added to my waste treatment bucket. In there I have pieces of angle iron. The copper cements out on the iron as metallic copper. But it is contaminated with other metals. The metallic copper is then thrown away. The acidic iron solution is then treated with sodium hydroxide to render waste metal hydroxides. These are filtered out and disposed of.
KEV YOU HAVE NO IDEA ON HOW MANY PEOPLE YOU HAVE INSPIRED OVER THE YEARS YOU'VE BEEN ON UA-cam. IM ONE OF THEM. WE ALL LOVE YOU TERESA AND LISA. YOU ARE AWESOME 😊
Thank you!
Streetips thank you for the time you take to explain the process, and don’t be discouraged by those few thumbs down, thumbs down are the people who wants to learn the process but, they never liked schools, the minute they see that mathematics is the key to get ahead on this trade, they give you a thumbs down.

Bravo
You have, in my opinion, the very best videos out there on the topic. Thank you and please keep them coming.
Using Fahrenheit instead of Celsius. Can't be best video for that reason alone. :P

Good to see someone else who writes out the math to inquart their gold instead of the calculator online. Oldschool is the best school.
Seriously thank you so much your videos are the best. The detail is what makes them perfect. You would have made an excellent professor.
28:38 You should paint your floor black. It will make it easier to see any fine beads of precious metal that splash out during the steam explosion.

Awesome Vid explains a lot how to refine, never knew it was such a process. Very Cool
Gosh, I wish you were my neighbor so I could learn hands on
Just Wondering. Could you have melted the gold out of the mold without damaging anything?
You know what I just thought about something he was to tell me openly on here where you buy your gold and silver you with this many followers they would all be buying a the supplies that you use so they don't worry about it I will find it places to get it on my own thank you very much!

Welcome!
@@sreetips I do have a question…how does one procure nitric acid and hcl?
Also. Does the fume hood as well as this setup require being in a temp controlled environment?
I buy nitric from dudadiesel. HCl from ace hardware.
Not that I’m aware of
If you add silica sand to the gold melt with a bit of borax and just let it cool after melt, you can pull the hardened wad out of the crucible and whack it to break the glass and trash metal off the gold.

Great video! It was painful to watch that graphite mold break, but the nice shiny gold bar was worth it.
Also, I just ran your numbers. You got 100% yield on your refining! That's incredible for scrap gold. Most times, it is under karat by a karat or two.
I've had to break them before because too much borax in with the gold. I calculate 91+36+2 grams of pure gold. And I got 135 grams. There may have been some extra gold over the silver items that I added. And I added 5 grams of pure gold during the inquartation so that may have thrown things off a bit.
Thanks for the explanation of why you melt the silver in.
It's one of the most beneficial things I've ever learned.
I can only say God bless you.
Just watched this all last evening. Very interesting. I've just subscribed. Two questions that you may address elsewhere. 1. Does this all need to be done in one sitting or can it be left overnight and picked up? 2. Are chemicals the only way to do this or is there a less caustic way to extract gold?
Very informative as always thanks for showing the way Kevin very awesome video
Hi Streetips tbo you make the best refining & recycling videos on UA-cam I have a question on AP solution. I used the AP to scrap some motherboards my solution was dark green after that I took some scrap stainless steel and put it into the solution to pull the copper out. Now my solution is blue. What does that mean what kind of metal is still in the solution? Can I recover that metal? Thank you for your time, I know it's the
MrErikm stainless has other metals in it chromium nickle aluminum and others I use a good ol piece of iron to drop copper from solutions leaves for cleaner waste yours now has thoes other metals in it making it just as nasty as before I'm not sure how to recover these other base metals others hopefully will add to help u fix it good luck ...
thanks man
Great video as always kadriver. See you in the group. You too sonny, sexy bastards!
Enjoyed the video as always Sreetips, thank you for making your videos.
excellent step by step video, thanks for posting... nice bar !!!
Great show just curious what you would of ended up with if you skipped putting it into solution and did your melt right after the nitric.?
Greg, I've had it assay between 992 to 998 doing it that way.
Thanks for the information brother this explains my last comment question lol kickass 😎👍💯🇺🇲🍺
Can you do this with computer scrap bars, and should the ice cubes that you use be distilled water as well?
what are the best hood vents to use. affordable as well. thanks. enjoying the videos
I'm partial to my Labconco. It has fiberglass interior and a built in fan. It was cheap ($250 on eBay) and it was easy to install.
You are a professional , the best 😎❤️
Thank you
thanks for the video. may i know why u need to do the aqua regia step 2 times? hope to hear your reply.
Each time I dissolve, filter, precipitate the gold gets cleaner through each cycle.
@@sreetips Ah isee noted. that means because in this video after the first aqua regia you deem the gold was not cleaned enough hence you thought it was necessary to do it second time in order to get a cleaner one at the end. thanks for the answer! appreciate it.
Your videos are fantastic and very thorough. Can you please do a start to finish video on processing MLCc’s.....
I've never processed those. But I'll do a video if I can get my hands on some.
Sir, you listed an "in-depth" formula recommended by a viewer in a previous video. I have forgotten which it was! Could you refresh my memory which one it was?
Thanks!
Fantastic video. I am getting real close to trying my first attempt. The one thing I have a problem with are the fumes. Ok, they go up the flue but them where? I can’t afford a professional scrubber. I just don’t want to harm the dogs if they are walking around my shop. Do the fumes dilute to a safe level once They are sucked outside?
Thanks and a wonderful video.
The fumes can cause serve distress several weeks after exposure. Frequent exposure in large amounts can kill. Keep the fumes away from people and pets.
"Back up" haha I love this guy. Great vid
brilliant video best ive seen. when you pour the aqua reqis through the filter doesnt that disolve the filter and the smb used for recovery. can that just be washed off as it always stays as a white powder at the bottom of my jar
the filter will not dissolve. But it will disintegrate in hot aqua regia. SMB is soluble in water. It can be rinse from the precipitated gold powder easily with water. But I have melted gold powder in the filter that is sopping wet with SMB. It doesn't hurt the purity of the gold.
What kind of filter do you use. Do u have to cool the solution down first??
I use a lab grade filter paper that I purchased on eBay. Number two or medium flow. Silver chloride is slightly soluble in the chloroauric acid solution. If the solution is hot then the chloride will stay in solution and pass right through the filter. But it is less soluble if the solution is cold. After adding ice (or by adding cold water) the silver chloride will come out of solution and the solution will turn cloudy. Then some of it can be filtered out. This is the main reason for cooling the solution.
Did you make a video of recovery of metals from the mud in the waste bucket?
Can you do a video about how to begin in this hobby? For someone who knows absolutely nothing about it? How to start learning, safety, equipment, etc?
I’ve documented the whole thing from when I first began 12 years ago. I’ve left nothing out.
loved that video mate, the length was good too. is it just my end or have the last 2 videos been much much quieter i can hardly hear you at your desk at all
Got it, I'll speak up and increase the volume with my voice.
i love thease videos streetips, by the way you look like super man just saying please keep them comming more 999 please
Just watched you refine scrap gold into 4.8 oz ingot, and WOW you have a new fan!!!!! Would like to know if, and how I can buy one of your ingots!!!
I'll be doing a gold filled scrap video soon. The pure gold ingot will be offered for sale in the video pointing to my eBay store.
Your videos are awesome keep them coming
the first man to pour acid onto his gold was a brave man
Fantastic video.. Do you have to have a large amount of gold jewelry to make it worth the trouble?
Yes, I get it faster than I have time to process it.
Great video !
What type of torch and crucible materials were used to melt the karat gold and sterling silver ?
Oxy/acetylene torch with a small cutting head and fused silica open-face type crucible/melt dish.
You are a pretty good chemist. The only think I don’t agree on it ever using tap water, I know sometimes it don’t hurt but I feel if you use to different waters you may not be thinking good accidentally put tap water when you should put distilled water. That’s just me.
I'm not a chemist. I do this as a hobby. After refining thousands of ounces of silver and hundreds of ounces of gold, knowing when to use tap water and when to use distilled water just kind of comes naturally. I've never accidentally poured tap water into a silver nitrate solution. Not yet anyway.
You add sulfuric acid to precipitate lead (if there is any). Does any jewelry typically contain lead, or are you concerned about lead that may have been in solder?
Thank you for your videos! They are very detailed and explanatory. I enjoyed every single second of every video that I have watched so far on your channel.
Could you please tell me the concentration of the first nitric acid you're using for the inquarted alloy and the concentration of the con nitric acid you've used for the aqua regia treatment? And also, it would help a lot if you could mention these concentrations in your next videos as I am sure some of us use your videos as a step by step guide for the process. Many thanks and keep up doing these brilliant videos
Someone said in a previous comment that "you may have spawned a new generation of refiners" and he might be 100% right. Personally I didn't know I could enjoy this so much until I accidentally found one of your videos, and then it hit me
The nitric acid is 68 to 70 percent concentration I buy from gfs chemicsls
Thank you, Sreetips!
WOW Im gona watch this video over and over
that turned out very nice brother very nice thanks for the video
I'll have to say you do awesome work. You should get your name out there using Facebook becoming a member to some of those gold prospecting groups there's a lot of them
I was invited to join one, and I did. But I can't remember the name of it.
Another cracking video and a great lump of gold at the end. The sound levels were very quiet at some points in the vid though.
I'm checking into a new camera that has a wireless mic so that I can be heard clearly at all levels and ranges. Plus I'll speak up in the future.
All this equipmetn torches, thr airvent acids do i need. Liscense because i want to do this too where could i purchase these items for my refining
Well done. You could also title this, " how to make 100% pure gold"
Can your calculations be used with Copper instead of sliver?....Thank you.
Amazing video. Quick question is the silver lost or do you recover that separate? Thanks.
All the silver is recovered
Again ! good video, looks like fun with a lot of tedious work.
I really dig (like) your videos.
I have seen almost all.
Plz, sir, could you explaín on a more molecule explaining of what he is going on. Ty
I’m not a chemist. I couldn’t explain it because I don’t know how. You don’t have to be a chemist to refine gold and silver. Platinum is a whole different story.
I know this videos two years old but I have a question where do you purchase your scrap gold and silver? Thank you in advance for telling me I really enjoy your videos!
Yard sales, thrift stores, flea market, resale shops
Sreetips, great vid. Question regarding breaking the mold (as someone who hates wasting stuff as I am sure you are): could you have hit the gold with the torch for a while to melt the flux and a bit of the gold, then dumped out of the mold?
Possibly, good suggestion.
Have you ever gotten the Nitric stains on your hands?
I wear gloves to prevent it
You use a gas flame above the melting temperature of gold. Is the weight of the dry gold any different after you melt it? Do you lose any gold? I see the golden dirt compresses into a solid. Is there a weight loss? Thank you. Is the extra heat used to evaporate the impurities? I bought an electric 3K furnace to see it is can improve on the process. Gas is quicker I think. It takes 45 minutes to melt .5 kg of gold in an electric furnace.
There are losses all along the way. I don’t know the amount of loss. I’ve never taken the time to measure it.
Yes I'm new. I want to know what is more feasible, forging or chemicals and acids.
what's the purity on that bar?
You my Friend are flipping awesome. Love your vids
Mike, in these placer gold videos I was searching for a way to extract the pure gold without having to use any nitric acid. But my preferred method would be to inquart the placer with silver and then part with hot dilute nitric acid. Inquarting and part with hot dilute nitric gets all the impurities out. Then I can usually get pure gold with the first aqua regia refining. Thank you!
How would you recommend to refine gold in form of very thin flakes from industry scrap? Its beyond paper thin but a lot of leefs, like 1kg.
What aboit meltimg it down in a furnace first to het some bigger nuggets?
I got some flakes in water. Added a drop of nitric, turned clear blue, no gold present.
I have one question. so your total yield ended up being about 5 grams more than the calculated amount of pure gold for each karate, is this because some of the jewelry melted most likely contained more gold than the stated karate? PS these videos are so great and informative. Thank you.
Very unlikely. Most karat gold is under, not over, in the amount of gold it contains. I probably tossed some higher karat gold in to a low karat bin because the marking was rubbed off.
I love your videos and great information as always. Have you ever calculated the cost of your materials (electricity, acids, smb, etc...) for purifying the gold, silver, and copper per gram? Just wandering the profit from purifying.
Jeremy, I do this as a hobby. So I don't keep track of expenses in that amount of detail. But it could be calculated based on purchases.
Do you have a video for the copper and silver you took off with the nitric acid?
The silver and copper solution: I get the silver one of two ways, either add clean pieces of copper to the blue solution to "cement" the silver out of solution, or add hydrochloric acid and precipitate pure silver chloride, then convert the silver chloride to pure silver metal with lye and sugar. The copper, not being a precious metal, gets added to my waste treatment bucket. In there I have pieces of angle iron. The copper cements out on the iron as metallic copper. But it is contaminated with other metals. The metallic copper is then thrown away. The acidic iron solution is then treated with sodium hydroxide to render waste metal hydroxides. These are filtered out and disposed of.
