Someone on that channel said it would be neat to see a silver and gold chess set. Still just learning refining, using a torch or a home made furnace, home made vacuum chamber, how to identify the jewelry and everything else. It takes time learning all that and casting the metals is an art. It was nice to see some of your crystals get cast into something.

Those were gold beads. They are normally hollow. But I let some in that were gold plated over plastic material. The balls that I removed were balls of ash. They wouldn’t have caused any problems. They were big enough that I could pick them out with tweezers. Otherwise I would have just left them in, no problem. The main problem is that I counted them as karat gold. So my yield will probably be off a little.

Sodium chloride brine electrolysis would negate the need for inquaurtation. It converts the gold and other constituent metals into a very finely divided mud. I don't know how silver would react to the nacient chloride reaction, but it takes the gold plating layers off of plated phosphor bronze quite readily. There is no need to process the bulk of the core base metals, so there is also the effect of concentrating the gold content by leaving much of the base metals behind. If nothing else, it reduces the requirements for acids in the processes afterward.

Hi. I'm new here and really love your channel. I have a question though, maybe 2. I have a lot of e-waste material like mainboards and old pci cards and old gold painted watches and so on, kilos and kilos. I figured I remove the components that could be of value as they are, such as EPROMs, Coils, Tantalum Caps, Inductors and some ICs. Most of the other components, such as resistors and caps are not worth a lot and I left them on the boards. Now the idea is to break the boards apart so they fit into my plastic container in order to give it a chembath so I can extract all the metals from the boards and the 9k jewlery. From the videos I've seen so far I know that Nitric Acid will break down every metal, except Gold if I just give it enough time and some bublling action or heat it up, please correct me if I'm wrong here, maybe I missed something but as far as my monkey brain understands, Nitric Acid breaks the metals such as Tin, Silver, Copper and Aluminum (or Aluminium) apart. I suspect there could be some other metals on the boards or inside the watches that don't get dissolved in Nitric Acid? Anyways, if I'm correct the Nitric Acid should take out everything that isn't Gold, I would pour the solution into another container for later possible silver extraction (using copper rods). Once I see no more stuff reacting with the Nitric Acid I would prepare 3 parts of Clohidric Acid and 1 part of Nitric Acid in order to obtain the Agua Regia to dissolve whatever gold is left on the boards/jewelry. Bubble action again, or heating it up to make it faster ofc, and transfering the solution into another container until there is no more yellowy reaction going on in my fist container (there should be no gold left then I guess). I would then add sodium metabisulfite to precipitate the gold from the agua regia solution and heat the obtained powder in my table furnace into a blob. Please tell me if the plan is correct and I understood everything correctly, or maybe explain a different, better approach. Could I maybe directly make Agua Regia, extract all metals with it and then just precipitate the gold and toss teh rest? I don't trust ChatGPT and don't wanna blow up my workshop xD. Really looking forward to a professional opinion from someone that does this stuff by the day.
@apveening
Ай бұрын
I don't do this by the day, but I think I am pretty knowledgeable about this. Nitric acid will also leave Pt group metals (PGMs) next to the gold. As far as I know, those are pretty rare in computers, so no real need to worry about it, just so you are aware (and don't toss them away). Basically, you are correct. You will get better results with the first method, but the second method (direct to AR) is quicker, but you will toss silver (and possibly PGMs).

Thank you as always, can never get enough of these videos. One more question. When inquarting, say you don't have enough gold to make 6k gold (I have some grips for a 1911 I won at auction for 120 bucks that have 20% of their weight being made up of 8k gold and I don't have enough gold to get to 6k)... is there much harm in having a higher ratio of silver to gold?

8k gold can be boiled in hot nitric as is. No need to add additional silver to the gold.

@@sreetips I have found that my autism often leads me to not fully communicating all the important information, my apologies for that. I should have noted the 8k gold is 'welded' on top of the silver. It could just be my limited knowledge but I don't see a real option other than melting it all together. It is a very ornate design going across the entire surface so cutting it out isn't an option.

If the 8k gold is welded to a piece of silver, then I’d just boil the whole thing in dilute nitric. The silver will dissolve completely, the 8k gold is low enough gold concentration that the nitric will get all the silver out of the gold too. If you boil it long enough

Quick question regarding your calculations. Where is the 1.265 for 14K and 0.635 for 10K derived from? If you're inquarting, would it not be simply taking the weight of each Karet multiple it by 25% to get the amount of silver would be needed to lower the Karet for recovery via HNO3?
@sreetips
25 күн бұрын
No, because the karat gold contains silver and base metals that must be accounted for when calculating the amount of silver to add.

@@sreetips I see. Correct me if I am wrong. If I have a 38 gram of 14K bracelet. The gold content of that bracelet can be calculated by part to whole division. 14k/24k equals 0.58 or 58% of pure gold. Then would you inquart 0.145 of silver to knock down the karat?
@sreetips
25 күн бұрын
38g x .583 = 22.15g pure gold times 3 equals 66.45 - (38g - 22.15) = (66.45 - 15.85) = 50.55g x .95 = 48.02g sterling to properly inquart 38g of 14k. Or just multiply 38g time 1.265 = 48.07g sterling to properly inquart 38g of 14k. The last digits are insignificant.

Why does adding ice sometimes put Silver Chloride in the Gold?
@sreetips
Ай бұрын
Because silver chloride is slightly soluble in hot aqua regia. Adding ice causes it to come out of solution so that it can be filtered out.

Also, if your stannous tests smoke yellow, its because of excess nitric correct? Thats what i believed anyway, i added a lot of SMB (to avoid Urea), and my 1st drop had gray/brown crystals with gold mud inside rhem and beside them. Luckily hot water fixed it all in the end, but thats the 2nd time in hundreds of runs over years that i had those crystals, first time a decade ago, they were green/yellow crystals. This time, I just remember my stannous test smoking yelleow, and having to add a whole lot of SMB before any color change or gold drop. It was a scary moment that still has me puzzled 5 days later. I tell myself it was to much nitric (im usually using Sodium Nitrate), and then to much SMB to neutralize it. But im honestly unsure. Good news is you rarely, or likely never lose the gold in solution forever. But sometimes you must worker 10x harder to get the gold back because you made a mistake. And that day i made some mistake. But the fix was easy, fortunately for me.

I use evaporation to drive off excess nitric. It’s far superior than adding reagents to kill excess nitric. It’s easy to do, it works every time, just takes a little longer.
