Hey Sreetips, somehow I have become your biggest fan. You’ve interested me in refining enough that I finally have a new hobby. First since your other hobby (guitar) when I was 14. So, I’ve pretty much mimicked your lab and have begun my journey. Loving it. Thank you for the inspiration
Hahaha this guy is awesome, here I am expecting him to say "I have been collecting this scrap for 2 years" he says 2 months.. the agony of waiting. Love it my man.
I work in computer science and chemistry was never my strong suit, but I love these videos after a long day in the office. Seeing the various reactions during the process is somehow relaxing to me. Keep up the good work!
3rd times a charm!! I love this one alot too! You don't make a single mistake, but you point out and show examples of what happens when you do leave out the step of incineration!!! Great Video!!! Have a GREAT Day!!!!
Cannot believe what a difference one simple step can make in the physical appearance of the gold. In a way, it was beneficial for you in missing the incineration step on the one refining so you can show what a difference it can make. Thanks once again!
I only do gold filled scrap 2 or three times per year. So all together I've done maybe 15 or 16 batches. That's not very many over a nine year period. I remember the first time I incinerated the foils. I was astonished at the increase in yield over omitting the foil incineration. I've forgotten to to it many times. I need a check list. This time it was a valuable teaching tool.
Awesome video! Ive done this many times before , having had worked for a prominent gold jewelry manufacturing company for years, and i like your setup! Great video!
I can not tell you how much I appreciate you solving all of the problems in the entire world in an hour and a half. Yes, I do this much with my good friends, we feel we accomplish the task as well; and, as a species and a bunch of humans that need to care for each other, this thinking amongst contemplators, hopefully, leads to the beneficial progress of us all.
I meet with my friends, the college math professor, and the artist, every Thursday for lunch. We are all musicians. We've been doing it for ten years this summer. We have solved the problems of the world, over and over again, at those Thursday lunches. Now, if we can just get the world to listen to us.
Here is a video published by my mathematician friend, Paul Young, at the College of Charleston. He's a big-shot in the math world. He travels all over the world giving talks and works on new ways to use math to improve business and computers. He has found and published new number theories similar to Fibonacci and Mendlebrot. If you can tell what he is saying in this video, then you're a much smarter person than I. ua-cam.com/video/I9Bv_CycEd8/v-deo.html
Your the man!!! Wish I had a year to work hand's on with you it's to dangerous to try just by watching I keep watching because electronics is where I find all my scrap
I really appreciate your videos. Small changes in the chemistry or procedure can majorly affect the outcome. Do it right, do it consistently, and do it safely. For anyone who doesn't know, the brown fumes produced when he adds the nitric acid can easily be deadly and you won't even know right away. You'll just suddenly find it really hard to breathe. Nitrogen dioxide makes carbon monoxide look tame by comparison. Don't try any of this without a fume hood and/or the proper respirator or do it outside and stand away while it''s reacting. Chemistry done right is a fun and rewarding hobby. Doing it wrong can really hurt or even kill you.
Folks are requesting my refining services. But I'm recommending you to them because I don't do any toll refining. I'd rather stick to refining my own material and making videos. I couldnt imagine having someone else material in my shop.
Very nice looking button! I love the fact that you explain your error from the previous video and show the difference... Keep up the educational videos!
Just wanted to say thank you. My brother and I are eager to start refining our own scrap. We are both learning so much by watching your videos but know that we still have a long learning curve ahead of us. I also need to research where to purchase the equipment necessary and look into building the proper workspace for safety. Thank you.
This stuff is the reason why I now wear an FR coveralls! Forget to remove one little stone, or, piece of plastic and, "POP", goes the burn dish! I got tired of picking molten metals out of my chest hair and beard, (I always wear a full face respirator while burning, along with the gloves, my son got me, made of, "CARBON X". Next generation heat protection)! I also just tweaked my torch, with a new brass tip. It has a huge center bore hole and puts out way more heat! I'm probably running temperatures that aren't recommended by the torch manufacturer, but, nothing ventured..... It works. I did have to invest in Comercial Bottles for Acetylene and O². I go through allot of gases! The down side? Actually lifting and transporting the gas bottles! Titanium shoulders don't mix well with 250 pounds of gas bottle! It's worth it though. This just never gets old!
George V yeah that’s what I am working on now, I have got some materials together to build a fume, I got wood for the frame, plexiglass for the body, ceramic tile as the base, with a activated charcoal filter, air duct, but I am looking for a fan, that way I can build a fame to hold the filter and the fan together, I don’t know if I will need two fans, etc. I have a piece of steel vents that I was looking at to place the activated charcoal in and I wanted to mount the fan or fans behind that. As soon as I get a fan I can see how tall I can make the fume hood.
Awesome video! I really enjoy your videos and i bought up some old chemicals in a estate sale where i found at the bottom of a crate some 95% pure silver wire and i weighed it and there's over 2 pounds. I payed 30.00 for it and got a nice power supply!
Sreetips I want to say how much I enjoy your channel and your videos. That being said, this is the last sreetips video I will watch.....that is until the NEXT sreetips video comes out as I have watched all of your videos except the one where payment was required. Thanks for everything and for teaching me alot about refining precious metals. I look forward to the next sreetips video. Take care and God bless.
You are a legend and that’s one beautiful button. Need a protege or someone to help you and pass down the knowledge too? I’d love to learn these skills and have this knowledge and would have a lot of fun doing this hobby
If I thought I could pull this off in my one bedroom apartment without poisoning myself and my neighbors, I think I could do this after watching every single Sreetips video. I actually do. Maybe one day…
When you do your inquartation, I know you generally use silver as your addition to the karat gold to save on nitric. Have you ever tried (or even considered) using gold filled instead? I know you probably have more than enough sterling scrap on hand at any given time to co-process with your karat gold, but it would be interesting to see if gold filled would also fill that role should someone run out of sterling.
Yes, gold filled can be used instead of silver but I've never done it. Too chicken. Scared I'll get something in there that causes a problem with the karat gold refining.
....im a newbie in this field now i have collected 700g of gp pins from RJ45 connectors, hoping to get gold from this. Watching your video, i think i do have now a PROFITABLE and EXCITING HOBBY.. THANKS
Any time you convert paper dollars to gold you experience a gain. Especially if you put the gold away and forget about it. Smash the idea of reselling it “for a profit.” Store your wealth in gold that is rising rather than in paper that is declining.
Would it not be easier to use a mesh under the gold during the incineration step to give tin/lead a path to escape? Something like a scoop used for deep fryers would work well to give a path out and still let you move to the dissolving beaker. Was watching one of the silver cell videos and was wondering would it be worth it to add a pneumatic piston to the build on a timer to crush the crystals every so often yet key anything sensitive to chemicals out of the fume hood area? Depending on the force needed it would push down till it compacted without over pressing and risking a blowout like a hydraulic piston would in the glass.
That's high tech. I've never tried using a mesh to allow solder to fall out. It's best to remove that material before putting it in the melt dish for incineration. But every now and then some will get it. It's easy to remedy, just pull out the good stuff and let the solder re-solidify them remove it and continue on. Before I built a pneumatic piston I'd just convert to a large 3.5 liter cell in a stainless steel bowl. The crystals grow differently in the stainless bowl and don't have to be pushed down very often.
Never tried that, I don't know. SMB is easy to get on eBay. Or just use copperas (ferrous sulfate) which is plant food. It precipitates the gold, all the gold, and nothing but the gold.
just curious, @sreetips ......where you crystallize silver from a solution, can the same be done with gold in solution? The clarity of the solution in this video seems perfect for it. Would be a beautiful piece of art if you could and would be 100% Au, I think.
Would the yellow color the solution tuned when adding HCl the first time not represent base metals coming out? The nitric should have burnt off during incineration.
Maybe. But I’d hate to have to sit there and pick out the remaining base metals with a pair of tweezers. I’d rather let the nitric acid do all that work for me.
Noticed you were using MAP gas at the end of the video, does MAP gas have a tendency go out when you tip the canister sideways similar to how propane go out?
I have not experienced that with MAP gas. But the flame does degrade buy fanning out and losing heat if I disturb it with the other torch. To remedy I have to cut the MAP torch off then turn it back on.
Are you getting any closer to your own UA-cam Channel?? I've been keeping an eye on my email!!! The best and fastest way to contact me is through commenting on one of my comments!!! I'd love too be one of your first subscribers!!!
@@shaneyork300 no I'm not, some personal things came up and it has been taking all of my time, the way it looks it will be a few more months. Thank you my friend.
@@sreetips thank you so much for actually writing me back. Up until a few days ago I had no knowledge of home gold refining even existing. I have serious interest in building and starting my own home refining lab. Your videos are excellent and I appreciate the detail you explain. I have zero chemistry or metallurgy background but I will be starting my learning and practice journey soon.
HELLO THERE SREETIPS YOU DO EXCELLENT REFINING VIDEOS !!! AND YOU SHOULD BE MAKING THE ACIDS THAT YOU MAINLY USE YOURSELF AND THEN YOUR PROFIT MARGIN WILL GO WAY UP JUST A THOUGHT YOU MIGHT CONSIDER???
I cut my teeth melting in those open face melt dishes and an oxy/acetylene torch. It's fast and cheap. I have an electric furnace. But I use it mostly for melting cement silver. I've never melted gold in the electric furnace.
Here’s a question. How come you drop hot metal into water in a glass container? Is it fine cause there was enough water to prevent thermal shock? I ask cause I’ve broke glass before. I welded up a door on a semi fixing something that broke and when we threw water on it the glass shattered. I’ve never done that again.
@sreetips can you tell me or link me what kind of tubing you use for your vacuum pump and your water recirculating? Your's always looks nice man gets beat up please and thank you
The clear poly vinyl (PVC) is from the hardware store. The black hose coming from my vacuum pump is standard rubber air hose from Harbor Freight. The line that connects to the flask is a reinforced tube used for the sprayer in a kitchen sink.
Joe, thanks for your interest. I'm going to build an electrolytic gold refining cell. Also, i would like to make a short video on turning a white gold mothers ring (multi-colored junk stones) into a nice 1/2 carat diamond ring using five nice 1/10 carat diamonds from a scrap ring that I purchased recently. . I'll show how to remove the stones from both rings and then set the diamonds in the mothers ring. Sell it on my eBay store.
Hey Kevin. I just want to say I love your videos. .. I cant remember what you put the silver button in to clean after it has been refined. Is it H2SO4 or hcl.
Question: if all of the metal is first dissolved in aqua regia and then metabisulphite is added to make it precipitate, then do nitric boils , then redissolve the gold after. Would the extra surface area from having all of the metal powdered help remove the need to enquart it because there wouldnt be any trapped base metals?
Trying to dissolve karat gold in aqua regia presents two problems. First, the hydrochloric acid in the AR will react with silver in the gold and form a passive layer of silver chloride that shields the gold from the acids. Second, putting all the metals in solution makes a very dirty solution and causes problems during precipitation. If done correctly, both problems are solved with inquartation. One of the most beneficial refining techniques that I’ve ever learned.
Sreetips great video as always. I would like to make two comments/questions. 1. What would happen if you placed the three buttons into a crucible and melted them into one button? Would the discolouration contaminate the whole content or would it diffuse and the new larger button be nice and shiny? Does any of that harm the value? 2. Would it be possible to have you occasionally tally up (just roughly if the exact is not possible) what the gold you end up with is worth versus what you spent to purchase the items you refined (or what you think they are worth on EBay) plus the cost of the supplies you used up in the refining process. It would be interesting to see a net $ result sometimes. Thank you for the content it is greatly appreciated.
I'll be melting all three of those buttons together to make an anode for the Wohlwill cell video coming soon. They will alloy together forming a single mass that is about 99% pure gold. The contamination from the ugly button will ruin the shiny appearance of the big button. But since the big gold button has more mass and higher purity then the ugly button, it (the small ugly button) will enjoy a greater upgrade in purity while the other two will malign only a slight down grade in purity because the ugly button is so small.
@@sreetips Thank you for replying Sreetips. If you ever have a chance to ponder my second point I think it would add a lot of interesting value to your already fantastic content.
I've thrown some numbers out from time to time. Keeping meticulous records of the cost of each batch would be interesting. If I could only find the time to make it happen. I'll try.
Hello .. thank you for sharing your knowledge .. if in the scrap you have Palladium and Silver ... how would this process of recovered and refined continue? Can you upload a video of recovered palladium and silver after obtaining gold with Nitric Acid? Thank you Marcelo
Marcelo, I already have a video uploaded. Silver cell slimes is where those metals show up. Please see the video that I produced on how to process the silver cell slimes.
Great videos! So incredibly informative! Question though, could you use muriatic acid instead? I would think it’s cheaper. Just looking at the bottom line
Nitric is the way I learned it from some professional refiners on the goldrefiningforum.com I think that hydrochloric would form lots of salts. Nitric is clean and fast.
sreetips thanks.... I am by trade a ceramic artist w a love of crystalline glazes. I don’t have a formal education on it but I’ve learned on the way. I’ll really appreciate the way you break down the why’s and how’s. I have a ceramic studio already w plenty of dangerous chemicals and your techniques are applicable to my setup. Thanks again
Very good and hard work!🤗 Question: It is not easier to use this gold filled scrap to do the inquartation when you are refining a batch of carat gold scrap rather to use a lot of chemicals for a low yield result?
Probably just dirt and debris. But there may be traces of PMs so I always save all my filters. I'll make a video on how I process my filters to get the precious metals.
Great video again. 4.7 % yield !! That's crazy. You must have selected some kind of very high grade gold filled ? Are you sure you didn't have some low kara solid gold in that batch (that would explain why you got so much brown sludge)? The best I ever had with 20 microns gold filled (and more) turned around 1.8 % ... !?
Let's see - he started with 417 grams of GF scrap of unknown karat purity. It was probably a mix of 1/20 10K, 1/20 12K and maybe a tiny bit of 1/20 14K. So the GF content was 1/20th of the total weight, or 5%. If it was all 12K GF, then 50% of that GF material was actually gold - meaning that 2.5% was actual gold. 417 x 0.025 = 10.425 grams theoretical yield. If it was 10K, then the theoretical yield is 417 x .05 x 0.42 = 8.687 grams theoretical yield. So, yes - the yield obtained was far too high for it to all be gold filled scrap. Either that, or my understanding of the amount of gold in GF jewelry is incorrect.
Three questions. 1) If you dissolve the powered gold one more time, wouldn't that make it come out a little more pure? 2) How would you make that one button from the last video clean up to look like the other two buttons? 3) Wouldn't it be worth your time to melt the buttons onto a one ounce bar before putting it up for sale? I'd love to see a video on the last two questions. Love the videos.
Yes, all of them should be refined a second time for high purity. But I'm saving those buttons for my Wohlwill cell video. Electrolytic gold refining cell.
Hey Sreetips, somehow I have become your biggest fan. You’ve interested me in refining enough that I finally have a new hobby. First since your other hobby (guitar) when I was 14. So, I’ve pretty much mimicked your lab and have begun my journey. Loving it. Thank you for the inspiration

It exhaust thru a six inch PVC pipe up thru my roof. It's been running for 8 years, rarely ever turned off.

Where are you Sreetips, missing your vids!
Would the yellow color the solution tuned when adding HCl the first time not represent base metals coming out? The nitric should have burnt off during incineration.
That could have been iron, nickel, or even a little palladium.
Does the gold shell ever let go of the inside base metals enough that I can recover them without using up enough nitric to dissolve it away?
Maybe. But I’d hate to have to sit there and pick out the remaining base metals with a pair of tweezers. I’d rather let the nitric acid do all that work for me.

Great video !! @sreetips what would you recommend for someone starting out. How much did you spend in those 2 months collecting the gold material?
My wife got it from junk jewelry bags. It's hard to tell because she pays different prices for each bag. Maybe $100 for everything.
@@sreetips thank you so much for actually writing me back. Up until a few days ago I had no knowledge of home gold refining even existing. I have serious interest in building and starting my own home refining lab. Your videos are excellent and I appreciate the detail you explain. I have zero chemistry or metallurgy background but I will be starting my learning and practice journey soon.
Hoof, I was the same way when I got started almost nine years ago.
HELLO THERE SREETIPS YOU DO EXCELLENT REFINING VIDEOS !!! AND YOU SHOULD BE MAKING THE ACIDS THAT YOU MAINLY USE YOURSELF AND THEN YOUR PROFIT MARGIN WILL GO WAY UP JUST A THOUGHT YOU MIGHT CONSIDER???
Do you recover the copper brass material after ?
No, I can buy copper for cheap. It's not worth it to try and recover copper.
is melting the gold like that more efficient or do you not have a furnace?
I cut my teeth melting in those open face melt dishes and an oxy/acetylene torch. It's fast and cheap. I have an electric furnace. But I use it mostly for melting cement silver. I've never melted gold in the electric furnace.
Here’s a question. How come you drop hot metal into water in a glass container? Is it fine cause there was enough water to prevent thermal shock? I ask cause I’ve broke glass before. I welded up a door on a semi fixing something that broke and when we threw water on it the glass shattered. I’ve never done that again.
I’m using glass that is suitable for hot material without shattering
Uauu Gratulation is very beautiful
Always thumbs up thanks for je video's
@sreetips can you tell me or link me what kind of tubing you use for your vacuum pump and your water recirculating? Your's always looks nice man gets beat up please and thank you
The clear poly vinyl (PVC) is from the hardware store. The black hose coming from my vacuum pump is standard rubber air hose from Harbor Freight. The line that connects to the flask is a reinforced tube used for the sprayer in a kitchen sink.
@@sreetips thank you I will look on Amazon and eBay for the tubing
Great video.. usually you tell us whats up for the next project. Any ideas?
Joe, thanks for your interest. I'm going to build an electrolytic gold refining cell. Also, i would like to make a short video on turning a white gold mothers ring (multi-colored junk stones) into a nice 1/2 carat diamond ring using five nice 1/10 carat diamonds from a scrap ring that I purchased recently. . I'll show how to remove the stones from both rings and then set the diamonds in the mothers ring. Sell it on my eBay store.
Hey Kevin. I just want to say I love your videos. .. I cant remember what you put the silver button in to clean after it has been refined. Is it H2SO4 or hcl.
5ml concentrated sulfuric acid in 100ml hot distilled water for about 5 minutes.
My brother and I have solved the world’s problems a few times too.
We do it every week, once a week. I love having lunch with those guys. We've been doing it for almost nine years.
I was just wondering which parts of your exhaust blower is exposed to those corrosive fumes and what kind of damage is being done.
Only the blower fan is in the fumes. Everything is fiber glass
Anyway. Since you started refining, how much gold do you think you have recovered to date. Do you keep a log?
At least 50 to 60 Troy ounces per year over nine years. Estimate 450 to 540 Troy ounces, conservatively. Just an estimate here.
So interesting Sir. Much hard work..late nights..congrat Sreetips 🎸🔥
Question: if all of the metal is first dissolved in aqua regia and then metabisulphite is added to make it precipitate, then do nitric boils , then redissolve the gold after. Would the extra surface area from having all of the metal powdered help remove the need to enquart it because there wouldnt be any trapped base metals?
Trying to dissolve karat gold in aqua regia presents two problems. First, the hydrochloric acid in the AR will react with silver in the gold and form a passive layer of silver chloride that shields the gold from the acids. Second, putting all the metals in solution makes a very dirty solution and causes problems during precipitation. If done correctly, both problems are solved with inquartation. One of the most beneficial refining techniques that I’ve ever learned.
@@sreetips thank you for explaining me the process!
Where can I buy dilute nitric acid?
I'm wondering if you cut the jewelry up, exposing more areas of the base metals to the acid, if it would speed up the process.
Halloween111 I would agree too
Maybe, but it would add another step to an already lengthy process. Probably better to let the chemicals do the work.
Sreetips great video as always. I would like to make two comments/questions.
1. What would happen if you placed the three buttons into a crucible and melted them into one button? Would the discolouration contaminate the whole content or would it diffuse and the new larger button be nice and shiny? Does any of that harm the value?
2. Would it be possible to have you occasionally tally up (just roughly if the exact is not possible) what the gold you end up with is worth versus what you spent to purchase the items you refined (or what you think they are worth on EBay) plus the cost of the supplies you used up in the refining process. It would be interesting to see a net $ result sometimes.
Thank you for the content it is greatly appreciated.
I'll be melting all three of those buttons together to make an anode for the Wohlwill cell video coming soon. They will alloy together forming a single mass that is about 99% pure gold. The contamination from the ugly button will ruin the shiny appearance of the big button. But since the big gold button has more mass and higher purity then the ugly button, it (the small ugly button) will enjoy a greater upgrade in purity while the other two will malign only a slight down grade in purity because the ugly button is so small.
@@sreetips Thank you for replying Sreetips. If you ever have a chance to ponder my second point I think it would add a lot of interesting value to your already fantastic content.
I've thrown some numbers out from time to time. Keeping meticulous records of the cost of each batch would be interesting. If I could only find the time to make it happen. I'll try.
@@sreetips I would suggest looking at larger time frames for amounts. Month at a time maybe. If you get used to it then try by week or project..🤔🐶🐕
Hello .. thank you for sharing your knowledge .. if in the scrap you have Palladium and Silver ... how would this process of recovered and refined continue? Can you upload a video of recovered palladium and silver after obtaining gold with Nitric Acid?
Thank you
Marcelo
Marcelo, I already have a video uploaded. Silver cell slimes is where those metals show up. Please see the video that I produced on how to process the silver cell slimes.
Close to 5% yield so it should be a lots of 1/10 or even 1/5 gold filled high carat approx 18kt gold filled material in there.
There were some gold filled insignia pin in there that may have had some karat gold on the tops.
Great videos! So incredibly informative! Question though, could you use muriatic acid instead? I would think it’s cheaper. Just looking at the bottom line
I did use muriatic acid. Muriatic is just another name for hydrochloric acid.
sreetips sorry, I should have elaborated , hydrochloric first. Instead of the nitric
Nitric is the way I learned it from some professional refiners on the goldrefiningforum.com I think that hydrochloric would form lots of salts. Nitric is clean and fast.
sreetips thanks.... I am by trade a ceramic artist w a love of crystalline glazes. I don’t have a formal education on it but I’ve learned on the way. I’ll really appreciate the way you break down the why’s and how’s. I have a ceramic studio already w plenty of dangerous chemicals and your techniques are applicable to my setup. Thanks again
Very good and hard work!🤗
Question:
It is not easier to use this gold filled scrap to do the inquartation when you are refining a batch of carat gold scrap rather to use a lot of chemicals for a low yield result?
Gold filled can be used. But I refine silver also. For this reason it’s better for me to use silver to inquart.
@@sreetips Many thanks for this answer. Make sense. Kindest regards.🤗
Do you do things like silver plated plates and cups and other items besides jewelry?
Not yet. But I'm saving the plated stuff for when silver gets up over $100
@@sreetips Cool, thanks for the reply.
What does the sedament on the filter consist of
Probably just dirt and debris. But there may be traces of PMs so I always save all my filters. I'll make a video on how I process my filters to get the precious metals.
Great video again. 4.7 % yield !! That's crazy. You must have selected some kind of very high grade gold filled ? Are you sure you didn't have some low kara solid gold in that batch (that would explain why you got so much brown sludge)? The best I ever had with 20 microns gold filled (and more) turned around 1.8 % ... !?
Let's see - he started with 417 grams of GF scrap of unknown karat purity. It was probably a mix of 1/20 10K, 1/20 12K and maybe a tiny bit of 1/20 14K.
So the GF content was 1/20th of the total weight, or 5%. If it was all 12K GF, then 50% of that GF material was actually gold - meaning that 2.5% was actual gold.
417 x 0.025 = 10.425 grams theoretical yield.
If it was 10K, then the theoretical yield is 417 x .05 x 0.42 = 8.687 grams theoretical yield.
So, yes - the yield obtained was far too high for it to all be gold filled scrap. Either that, or my understanding of the amount of gold in GF jewelry is incorrect.
why do you have to remove steel? it won't dissolve in nitric?
Not very well.
Wondering how much of those foils blew away during that last incineration
nice job sir 👍👍👍😀👍👍👍
Three questions. 1) If you dissolve the powered gold one more time, wouldn't that make it come out a little more pure? 2) How would you make that one button from the last video clean up to look like the other two buttons? 3) Wouldn't it be worth your time to melt the buttons onto a one ounce bar before putting it up for sale? I'd love to see a video on the last two questions. Love the videos.
Yes, all of them should be refined a second time for high purity. But I'm saving those buttons for my Wohlwill cell video. Electrolytic gold refining cell.
