Most other videos I've seen they just make an arbitrary mix of aqua regia to do this and then ending up having to netralize it before dropping the gold out (I seem to recall urea can be used for this) or add the sodium metabisulfite very slowly to avoid having it go into thermal runaway. This seems like the better way to do it and it also saves on the nitric acid which can get pricey if you use a lot of it.

Thank you for your videos they close the gap between theory and practice. I just did a couple of things which seemed to work quite well (because it was in front of me) .... I used an ultrasonic cleaner (that I use for clocks) rather than heat to promote the reactions. This can simply be turned off if things get over excited whereas you can’t just make a system cold if driven by heat. The other thing that I have done instead of using caustic soda to neutralise things is to simply use some limestone gravel from the drive. This costs nothing and just sits there bubbling away until the acid is used up. This eliminates vigorous reactions and leaves the ph of waste solutions right where you would want them to be Many thanks once again for your efforts and I hope that my observations may either help or amuse.🇬🇧

Gray sediment with the gold, some stuff precipitating after filtering... adding water to the filter probably precipitated some silver chloride. In concentrated chloride solutions, silver chloride actually is somewhat soluble. If you dilute such a solution the silver chloride will precipitate. That is one reason to dilute a gold chloride solution before filtering. Chilling the solution will also lower the solubility of silver chloride.

I love your videos because you talk to us intelligently in step by step methods. I question inquartation, the need to add silver in to weaken the percent of gold, because you then end up needing to use 5-10 times more Nitric acid than you need. A simple solution would be to just melt the metals first and turn it into cornflakes or shot. Spreading out the metals into thinner pieces with more surface area would allow you to get to both the gold and silver. Another way would be to simply just grind the metals into shreds or powders. The other barrier I learned from you is that if you add HCL to Silver first it creates Silver-Chloride, an insoluble material that shields and stalls the chemical reactions. Again, a constant blending of the materials is needed to get into the center metals. Could electrolysis help to pull the silver-chloride ions away somehow? I like the sulfuric-electrolysis method. Creating a giant cell made of lead or stainless steel, like you do in the creation of pure silver, it can pull different metals away at different levels of density. Am I just dreaming?

Help! So I have successfully refined a small amt of gold from optical scrap using HCl and bubbler over time to dissolve base metals (mostly copper), then adding residual to HCl, adding nitric acid ml by ml til no further reaction, denoxed with sulfamic acid, then dropped the gold with SMB. Encouraged, I upped my amt of scrap by 10X. After 3 weeks of HCl and bubbler, I assume I jumped the gun and tried to dissolve the gold too fast. Ended up with a dark brown grey solution (weirdly, tried to stannous test…dipped paper was pretty brown but when stannous was dropped on, it oddly went clear???). So, I did the next “logical” thing… I panicked and tried to add SMB. Now I have a mess. I separated out the solids, rinsed and put back into HCl. The liquid still does what I would call a reverse stannous test (wrongly so, but I have no clue why it is clearing up the original brown solution). Is there still gold in there? I’m trying to wrap my head around the info in this video about introducing silver but I’m not there yet. Any words of wisdom? I sure could use some encouragement/ direction. Feeling defeated 😕

Hey there Mr. Sreetips! First off, just wanna say… big fan. You’re the man. I’ve found an invaluable amount of information through your works. Big thanks! I got a question for you. Let’s say someone decided to do their first refining, and somehow he stupidly throws a steel chain in the mix thinking it was silver, and somehow never noticed when he inquarted it. He then continues with the hot nitric boils, and dissolves less than half of the chain… I’m wondering if I should filter, then precipitate, and just start over? Would I have to do a hydrochlor boil to remove the iron ions? Idk… 😅😢 I’m stumped. Any advice or tips would be greatly appreciated.

I really enjoyed the video, but you could have made it better, since you offered no alternative to traditional SMB reducing method. For this kind of mistake the best reducing agent in FeSO4 (a.k.a copperas) because SMB can and will reduce everything in solution, this includes silver and copper ions that may be present. It shouldn't be a major issue since there should be little of both in solution, still to people that struggle to get their hands in SMB (like me) copperas comes as a common, cheap and preferable alternative. But a second refining step should be done, this time with a better reducing agent such as SMB or oxalic acid + sodium hydroxide to get rid of small iron impurities. Keep up the good work mate! Cheers

What to you use to percipitate the silver from your used nitric acid? I can't believe I haven't seen your method yet, especially after watching so many videos. Do you just use a copper push bar? Or do you use a chemical for silver precipitation? I've refined so much gold in Poormans AR over the years, all without inquarting sadly. And I neutralized the solution with Urea. And never recovered the silver, never even tried to. Now I want to inquart, and I see how you use Nitric just to dissolve the silver and other alloys before the gold sees AR. I'm just curious about the best way to get the silver back. Is it really as easy as putting a copper bar in the dilute, or used nitric just to cement the silver out? And I imagine it's a silver chloride that requires more than just a rinse and a melt to come back to metal form. Any info would be great. Thanks for all you do, you are a phenomenal teacher. 🙏

I add clean copper to silver nitrate and the silver comes out of solution, as the copper goes into solution, in accordance with the reactivity series of metals. But first, I add more sterling silver and some heat, to consume any excess nitric before adding the copper. Excess nitric in the silver nitrate will needlessly consume the copper that’s intended to cement the silver out. Silver chloride is a totally different process.

Is this the gold actually oxidizing?
@sreetips

No, the solutions are dirty because of all the base metals being dissolved with the gold. If the silver and base metals are removed first by inquarting with silver or copper, then parting with hot nitric, then the solution will be clear and orange with only the gold in solution.

What would happen if instead of adding the sodium metabisulfite to precipitate the gold you just boiled off the solution?
@sreetips

The solution is called chloroauric acid. If you evaporated off all the liquid then you'd have anhydrous chloroauric acid. Nerd Rage did it with platinum (chloroplatinic acid) but I think gold will do the same thing.

Any suggestions? I have a dirty solution of copper, gold and gold jerlery alloyed metals, most likely silver and zinc mostly, I added hcl by mistake, (no lable)🤔 when I was dissolving base metals, I need to extract any gold that may have dissolved but all that perciputated looks like a mix of smb and copper cloride? I don't know, is there a way to remove gold and recover from this newbie mistake? Please share your wealth of knowledge

You added HCl by mistake. If it were mine, id pour the whole mess into a filter and get all the solids filtered out. Then I'd put the solids, filter and all, into a melt dish, cover with a 50/50 flux of sodium carbonate and borax. Then I'd try like the dickens to get it melted into a button. Then I'd determine the karat of the button, inquart with silver or copper, and start the nitric treatments over. If it were mine.

@@sreetips ok so suposen I just saw your suggestion and I ignorently went on with the dissolution of gold, tho it was a long and painful weekend of improperly colored mess, I got the gold to mostly dissolve into a golden green liquid, left with a whiteish yellow semi solid in the shapes of my inquarted gold. Soft and spongy tho it SHOULD BE DISSOLVED, what a disaster, my first run was so smooth I must have relaxed far to much. This is entirely my doing and I truly appreciate your pitty. Thanks for the tips, I now know what to do, start over. Ill melt up what's left and see what's going on, it looks like some chloride husks, you would cringe. I'm ashamed

Its a ten liter plastic bucket. It's full of copper. The waste is bubbled with air and any precious metals cement out on the copper. After a few days the solution, now devoid of precious metals, and full of copper, is transfered to my waste treatment bucket. It's full of angle iron. The copper cements out on the iron and the copper metal is thrown away. The resulting acidic iron solution is treated with sodium hydroxide. The metal hydroxides are filtered out and disposed of. The caustic solution is adjusted to pH7 and disposed of. Nothing toxic ever gets poured down the drain.
