I would like to see him do a drop with electrolysis... it's similar to the gold cell but uses a carbon anode instead of gold, and the solution fades from gold-red to clear as it pushes it out. Like this it isn't "selective" (anything that will favor over hydrogen can be/is pushed out) but it doesn't contaminate the "drop" (plating). In fact you can keep it completely out of the solution by putting a bag around it like the silver cell. The only thing that will appear in it will be trace carbon that may have agitated loose. (Edit: Process is called "electrowinning")

Very interesting to watch. I could tell by the color of the precipitate that gold was contaminated. I was amazed at how it looked after the melt. It looked fake. It reminded me of gold I've seen in India, dull and plastic looking. I read a paper talking about this, and they recommended using Zn powder, bubbling N2 through the solution and fixing the pH between 2 and 4. This was a process to create ultra high purity for microelectronics.

In my experience, zinc will follow the gold no matter how many rinses, acid or water, are performed. In order to get that zinc out I’m going to have to refine it out. Including inquartation. If I tried to dissolve that bar as-is, filter and precipitate, then traces of zinc will still be present and make an ugly bar. The only way to get it out is to inquart.

Yes Mr Sreetips. Plus, for poor rookie refiners like me, I can use selective separation by using Zn or Al. Being Al something that pops out everywhere in my house. If we run out of SMB or any other reason. First, diluted NH3 boil However as alternative you can use pure HCl with highly concentrated H2O2, no Nitric (it is needed extra care here because it is very likely not all Au will go in solution in the first boil). Add small pieces of clean Zn or Al until everything drops. You go selectively separating the metallic salt, first with HCl, clean, HCl with low concentration H2O2. If Ag is present, after the first round of separation with HCl only, use in. 1:1 proportion high concentration HCl with NH4Cl, it will dissolve everything up to Ag. There are intricacies and further refining is needed to achieve better purification and it there are PGMs present. Just is just an abridged overview of this option if we lack of NH3 and SMB, or we want to save either or. There is also another alternative that involves boil in H2SO4 and a follow up boil in H2SO4 + H2O2 (I used this method this week to recover gold from sundry integrated electronic components). Not talking to much because it is dangerous and most refining communities have banned either the topic or the topic and the person who raised the topic. Points to consider: volume of waste generated, level of certainty that you do have all Au and up recovered. At the very end when, supposedly, you have only Au (and PGMs) in solution, one boil with a bit of Nitric is recommended to ensure the leftover salt (please noticed I use salt very loosely to refer to precious metals in cement or powder state. Some of them are salt, other are not even close, just to make annotations easier when making annotations of the experiment in execution) is pure gold

There should not get outside this scenario. We might want to evaluate the scenario of we have any known contamination during either equation. For the first equation, if there is Ag on the left side alone or alloyed, the right side is completely different. For every other scenario I did not achieve any scenario where pure Au is extracted.

You did that exactly the way I hoped you would every step of the way. Nothing at all to even be mad about. It was very very cool to see how that would work to try using zinc to cement gold, and I woulda been Kinda upset if you refined a third time because the curiosity in me needed to know if that would be at all a viable method of getting gold out of solution. I wonder if some sort of equation could get that process to work without any contimation. Like if you used the exact amount of zinc required and not a speck more, would the final Product be threw mines fine? I dunno but damn was that cool to see and especially how the zinc was replaced by gold so efficiently that the shape or the zinc sheet was still there only it was actually gold flakes that took its place. Overall this is one of the best and most interesting things about you, when you get some idea and try something just for the sake of trying it. You should try to do this anytime you have a curiosity about some aspect of refining, because it's just plain fascinating and not many people would have so much gold and so much equipment that they would be willing to satisfy these kind of random experiments for No reason other than childlike curiosity. One of the better videos in a long time and my one and only request would be a little less time-lapse, especially when you pour nitric boils into the silver jar. Watching that thick cloud of nitrogen dioxide erupt from the silver is one of my personal guilty pleasures and it makes me a bit sag to not get to watch them all. But that's just me, I get most people probably don't care about that so Much. Good work though. 👍

Using zinc is a nice idea, and should work just fine to drop gold, but I think I know what happened with the impurities in the final bar: with the vigorous reaction with the acid while dropping the gold out of solution (due to the abundance of HCl) you've trapped zinc inside the gold as it precipitated. Similar to how high carat gold prevents chemicals from reaching base metals, that zinc was locked up and not released or affected by the washings until you freed it again with your melting for the bar pour.

The gold containing solution is extremely acidic, so zinc "reacts vigorously" mostly with acid(s), I guess. If the aurochloric acid would be, or rather "could be" neutral then the reaction would be more like a piece of zinc dipped in cupric sulphide solution (CuSO4), which is also rather acidic, BTW. Speaking of which ("BTW") I think the actual reduction of gold here may be done by that "in statu nascendi" hydrogen - one released when zinc reacts with excess of hydrochloric acid, which hydrogen is substantially more reactive than "regular" molecular H2. It is capable of doing reductions molecular hydrogen cannot do - that is, H2 fed from, say, Kipp's apparatus, bubbled through a solution won't reduce it while hydrogen released "in situ" by a piece of dissolving zinc will do the trick. (There's some "textbook example" of this reaction, but I forgot what it was... ;-)

zinc might be too reactive to use as a method of dropping the gold - but what about inquarting with zinc? It might save you on nitric acid using zinc instead of silver. Will gold even alloy with zinc? I know zinc won't alloy with lead ("Park's Process" as demonstrated on Cerro Gordo galena by Jason over on MBMMLLC) but will it alloy with gold?
