If my teachers in school would have been more like you, I would have had more interest in it. It's a pleasure watching your videos and learning. Your awesome. Thanks for all you do.
Right on. It would have been so interesting to learn the processes of refining gold and silver in high school, with maybe a demonstration by the teacher over a few days. Instead, what we learned about chemistry was almost entirely theoretical, it was pretty much like maths for me. The most hands on thing we did was to get to smell ammonia and that didn't leave a good memory...
Just dropping a note to say thank you for not filling the quiet spots with some corny music. Silence is perfect. Thank you for making these interesting videos!
Beautiful stuff sir. Love watching the process of your work. The reactions are my favorite part. They can be mesmerizing to watch , and I watch intently. Love the show sir . See you on the next one
Another great video! I am waiting for gold to settle on my biggest batch yet. I think I should have enough scrap waiting to be processed to pay off all of my debt. This is the best hobby I have found.
Your gold refining results are superb!!! I'm getting myself ready to perform my first refine this weekend. I've done it so many times over and over in my head. I believe I'm ready. I've watched so many video's! Yours are so detailed, I will have the laptop close enough, that if I get in a bind I can just pull up a Sreetips video and get past the bind. Thank you!!!
@@sreetips I believe that you did the pins 4 months ago! I enjoyed that one too. I wasn’t sitting on pins, just eagerly looking forward to holding your artistry.
Your editing is getting really good. Your processes keep getting simpler. Thank you for refining the realiztion on "How to" for individuals as myself that can be motivative enough to follow steps for prosperity. Thank you.
Perhaps it's not the processes that get simpler but more stuff gets cut out. This may also include some subtle but crucial points about the process. So while it becomes more easy to watch this way, less information may be conveyed. Fortunately I also watched the old videos to learn from!
Luv your videos I'm a Ole prospector and did mine in nitric, also grabbed the gold&silver in mercury back in the day Jordan creek, silver city Idaho had a big spill of mercury in 1898 22tons of mercury in Jordan creek at Delmar Idaho ghost town I dredge all the gold I could get out of there ,thanks 😀
This reminds me of working in the Plating shops. They would refine the waste gold baths they couldn't send through IX exactly the same way you just did. They would end up with 4-5 bars almost the size of Twinkies, and almost the same color. But a LOT heavier.
The design on the bottom of the bar is very symmetrical... Looks awesome. I know it is just how it poured and all that, but those are definitely some interesting pour lines. 🤘
Just a quick comment: AgCl is somewhat soluble in concentrated HCl because it forms a soluble chloride complex at high chloride concentrations. It has practically no solubility in dilute HCl though. So while adding a few drops of concentrated HCl to a solution is a very sensitive test for silver, adding a few drops of solution to concentrated HCl is not very sensitive and may give false negatives. Excellent video in general though, as always! You've inspired me to do my own small-scale refining and it's fascinating stuff!
In the silver cell. The silver dissolves into solution and goes through the anode filter while the Pt will remain in the anode filter as slimes that I can process and recover.
Like always A great educational video Really enjoyed the whole video As a suggestion, please consider recovery and refining gold and other precious metals from electronic devices With best regards
Absolutely enjoy your videos, I believe I have watched them all, and yet a lingering questions always comes up as I am mesmerized by the results of your processes, and that is: the cost of chemicals that are used and depleted in these processes has to be a factor in the net value of the finished product. I have looked up some of these chemicals and they are not cheap by any means, especially with the quantities used in the multi step refining processes you show. how do you take the expense of the processing in to account when you choose to refine your products?
I don’t. Creating videos is my hobby. Most of my videos produce losses. The real money is made when the scrap is bought, not when it’s sold. You make your profit when you buy!
Can you melt after multiple nitric acid boils considering that whats left is gold ? Or in other words, can you skip the aqua rigia + smb step ? I know white gold is more complicated to refine so my question is pertaining to yellow karat scrap.
Great job, are you going to do a follow up video on dropping the platinum group metals out of the gold pour off water. Thanks for sharing, what a stunning bar of gold.
That liquid will contain much silver. I’ll cement out on copper, melt into shot, run through the silver cell. The platinum will get trapped in the anode filter of the silver cell. Then I’ll process the filters and recover the platinum from those filters.
Hello mr sreetips. It is so Nice to start the Day seeing clips from sreetips 😊. Clock is now ca 10 pm in Norway. Have a Nice Day sir, and take care. Great clip 🌠
Nice! Always love watching another refiner. It's quite unique the affinity that Ag/Pd has with one another. Interestingly enough the Pd will even precipitate out as a Pd Cl with the Ag i think that's why most refiners like it alloyed with Cu over Ag when sending it to them for further refining. The one that i found extremely challenging was the Pt/Ir alloy. Made me scratch my head a few times. Anyway....Great bar of gold. Maybe someday i'll get enough off my claim to send you a couple of 3 grams and let you make me a bar. Or trade?
good day. I have a question. I live in the Netherlands and want to distinguish myself here by separating metals, silver and gold. now you have to have permits for this to get the chemical products. is there an alternative by means of electrolytic, to be able to separate gold-plated jewellery, watch cases or silver-plated objects, or solid gold or silver from the non-precious metals. I would put safety first, so when purchasing, safety will be worked on first, but I want to know whether it is possible to do it here anyway. so hno3 is already becoming a problem just like the other chemical compounds.
@@sreetips Thanks. Looked up images of that and they look like various shapes of those magnetic ball clusters. Didn't realize it would probably take an electron microscope to see them. 👍🙄👍
Do you ever look for the other "whitening" metals from white gold? The Ni Zn and Cu could be close to worthless but and Pt or Pd could add a lot to the value recovered.
Do you do anything to sort the Ni white gold from the Pd white golds? I'm assuming you added the small amount of yellow gold for the Cu content to ensure a good color indicator.
Hello, first of all I would like to thank you for these masterful videos, and secondly I wanted to ask you if it is possible to metalize gold with potassium metabisulfite, or if it is possible to generate SO2 with potassium metabisulfite'? thankiu for your atention
do you ever test the waste junk from the filter to find out if lead was present? it would be interesting to see a definitive sulphuric acid lead precipitation
I just received my scrap gold, mix contains only some 1,7 g of gold, good enough for rookie experiments. I will try cupelation first. I bought also some 900/1000 damaged old medal (with ugly soldered ring), but it is so nice, I will try to repair it by disolving the solder. I find solder disolving solution on one russian chanell. If I mess up badly, goes into crucible, so not much to loose...
Where do you get your nitric acid? I got some on ebay that was decent for a decent price, but is seems like ebay is really limiting how much nitric is being put up for sale.
I just tested some old contacts for 1990's small IC chips with a weak aqua regia solution. I knew from a magnet test that the cores of the contacts were either iron or nickel-containing. But, there's another metal, possibly the plating, that's forming a brown precipitate in this weak aqua regia. It's puzzling. What do you think it could be?
@@sreetips Wish I had access to a mass spec. These older electronics had all sorts of various metals in them. You can never predict what the plating on the leads that looks 'silvery' really is. It's why I have to find a place with that sulfuric acid drain cleaner in stock! The sulfate chemistry works with so many metals, and is easier to perform selective precipitation in series. In my Chemistry Principles class, we did a reaction series which began with nitric acid, then went to sulfuric and then various other compounds to separate and identify 10 random metals in a starting amorphous sample. I still have the reactivity list somewhere among my piles of old college notes. I wish I could find it, it would prove very useful for this work!
There’s not enough to attempt a complete refining. I saved the white gold over time. I needed to pay some debts. So I decided to refine it and shoot the video. Just for the show. I’ll get it all when I refine my silver cell filters.
Your acetylene flame seems to be rather oxygen-poor, which lowers the tip temperature and increases the possibility of carbon deposits in metals that you melt. Is it on purpose?
I think its because gold needs to be a certain temp plus he's using a torch to heat it up to 1700c which is well below the 2200c they do at full power. Plus the carbon would just flow into the dish like lead does. that's why those dishes are used.
Do you have an opinion on inquarting gold with copper vs silver? Bad, okay, good? I have ounces of copper but not enough silver for my first batch and am unsure how to get more at the price I’m looking for. Thanks!
Hey sreetips, if you test a white gold item on the test stone that has palladium alloyed with it rather than nickel, does it appear to test at a higher Karat than marked if it is a gold-palladium alloy?
You may have made a video covering this but I'm curious to see the precipitation of gold in oxalic acid.. apparently it actually drops out into perfect little sheets of extremely fine gold foil or gold leaf(perhaps the method used to produce gold leaf?) Anyway thank you for inspiring me.
Sreetips you said in previous videos that you need to use Distilled Water because your water has Chlorine and that causes a reaction that you don't want. Do you make your Ice Cubes from Distilled Water as well?
sweet jebus, there was one point in your video where things go silent and i could hear a ringing noise, im already having hearing issues and i was thinking did i just go completely deaf, oh god, then the sound kicked back in lol

Advice: Do Not ask about "smelting" question when its obvious Mr. Sreetips is. "melting" I made that mistake and was thoroughly corrected by him... lol ive learned a lot since then... So, when will you make those amazing silver crystals again, and Do silver crystals cement out off nature similarly, thank you.... carl.
I have a question, hope its okay. How much .999 silver do I have to add when melting silver chain that has solder in it, to bring it up to .925? Thanks!!! :-)
Some times people use soft solder to repair jewelry. I add sulfuric whether I suspect the presence of lead or not. It costs nothing, hurts nothing, and provides a big benefit.
Hey Mr Street tips where do you buy your nitric acid the company I buy from is out of stock right now it's on back order and I need to get some I'd greatly appreciate it
Hello Mr Street tips was trying to email you but could not find your email address on your info anymore let me ask you a question when you're refining gold filled jewelry if you're trying to do it too fast with nitric acid will that deplete the amount of gold you get like if you add too much too fast would it subtract the amount you're supposed to get just wondering
Depends, do they include steel parts? Are they GF on just one side or both? Is the gold worn away in spots? If it’s good clean material and not all worn away, in my experience, a yield of between 2.5% to 3% can be expected. But it could be higher or lower. Also, yields will depend on the techniques and skill level of the refiner.
I basically was just wondering what do you think the weight of the goldfield material would be when I pull it off it would it be half or a little more or what
Yes, adding sulfuric will react with any lead that might be present, forming insoluble lead sulfate, and then it can be filtered out 100% - Lead, even in trace amounts, ruins the ductility and malleability of gold. Adding a touch of sulfuric hurts nothing, costs almost nothing, and provides a huge benefit. Leaned that one from Harold_V on the goldrefiningforum.com
I’d be interested to see if cleaning the walls of your fume hood would generate much gold. All of the stains are purple so there must be some gold there.
If my teachers in school would have been more like you, I would have had more interest in it. It's a pleasure watching your videos and learning. Your awesome. Thanks for all you do.

Hello Mr Street tips was trying to email you but could not find your email address on your info anymore let me ask you a question when you're refining gold filled jewelry if you're trying to do it too fast with nitric acid will that deplete the amount of gold you get like if you add too much too fast would it subtract the amount you're supposed to get just wondering
Gold is not very soluble in boiling nitric. Adding it too quickly could cause a boil over. But it should not reduce the yield by much.
Awesome 👍
I would love to see you recover silver, platinum or whatever metals you have in the collected waste also.
There’s too little PGMs to attemp a recovery of the PGMs only.
Mr Street tips if I bought 3000 g of men's gold filled watch bands how many grams do you think of that as goldfilled material
Depends, do they include steel parts? Are they GF on just one side or both? Is the gold worn away in spots? If it’s good clean material and not all worn away, in my experience, a yield of between 2.5% to 3% can be expected. But it could be higher or lower. Also, yields will depend on the techniques and skill level of the refiner.
@@sreetips goldfield on one side stainless steel on the other bands looking really good shape like damn near New almost

That was great thanks!!
hello, after the Precipitation, what happens to the sodium metabisulphite, since 99.99% gold. thank you!

Next time will you finish palladium or platinum from waste? Or better to see how to treat waste in an eco-compatible way? thank you
There are some videos about eco-friendly (and rule-conformant) waste processing on this channel.
Also there are videos about recovering Pt and Pd from silver cell slimes, which is where they will end up from this type of refining.
I notice you always say "just in case any Lead made it this far" but wouldn't the aqua regia just dissolve that lead ???
Yes, adding sulfuric will react with any lead that might be present, forming insoluble lead sulfate, and then it can be filtered out 100% - Lead, even in trace amounts, ruins the ductility and malleability of gold. Adding a touch of sulfuric hurts nothing, costs almost nothing, and provides a huge benefit. Leaned that one from Harold_V on the goldrefiningforum.com
I’d be interested to see if cleaning the walls of your fume hood would generate much gold. All of the stains are purple so there must be some gold there.
