    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.🇬🇧

    I was already sold on inquartation!! This was a GREAT demonstration on why inquarting is so necessary!! I've seen several others just do aqua regia method. When I saw the how clear the solution was that's all I needed to know!!! In fact you're the only person I've seen use inquarting method, but you're also the only person I've seen do karat scrap! GREAT VIDEO, keep up the AWESOME WORK!!!!!!!!

    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.

    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.

    If anyone wonders why you use silver for the inquartation. Silver has an atomic weight of 108g/mol vs Copper 63,5g/mol. That means that in 1g copper, you have almost 2 times as many atoms as in 1g of silver. By using silver, you are saving nitric acid, because you have to dissolve less atoms. Hope that helps.

    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?

    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!

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. 🙏

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.

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

    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.

    If too much silver is added then the gold will crumble into a powder. Then getting the solution separated from the powder becomes difficult. If too little silver is added then the nitric won't penetrate and dissolve the metals out. Adding the right amount results in chunks of gold that hold together during nitric boils making pouring off the solution a breeze.

    What was your material? Was there gold in solution? Did you test with stannous? How much gold expected? Did you inquart? Was there other metals in solution? Did you premix the AR? The list of questions goes on and on. There are too many variables. I couldn't begin to help because I don't know what you have there. My guess is that you tried low yielding plated scrap and you probably never had any gold in solution to begin with. A common beginner mistake. I know this because I made the same mistake the first time I tried to refine some metals.

    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.

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.

    If you add the right amount of nitric, only enough to just dissolve the gold, then there won't be any nitric to denox. But if we accidentally over shoot and add too much nitric then we don't use urea to kill the excess nitric. We use sulfamic acid.
