When I started following your channel, Sr. Chief, I did some stoichometric research on AR and I didn’t understand why you added the nitric in increments, but I reasoned that because you are the expert for these processes, you knew something not greatly discussed on the interweb. I just stumbled on this video and NOW I get it. Thank you for your entertaining instruction! 👍👍👊👊

I have bought some gold covered pins on EBay. Hopefully they will be ok for my first attempt.
@sreetips6 жыл бұрын
Gold covered pins are gold plated. There is a very thin coating of gold over a base metal. Usually brass or copper, but sometimes steel. Steel will not dissolve very well in nitric acid. Use a magnet to see if you have steel or brass as base metal. In any case, the amount of gold will be very small. And you must use a sulfuric acid stripping cell to deplate the gold. It would be a hard first-time experiment to pull off. I've done milspec pins by dissolving the base metal (nonmagnetic brass) with hot dilute nitric acid, then dissolving the resulting gold foils in aqua regia, but it took a long time and used much acid. Good luck with your refining experiments.

I'd also like to thank you I feel like with the instruction you gove in this video ill be able to reproduce the process. I have around 2000 grams of recycled gold bars, I'm going to melt them down into little bb sized shots and then use your instructional video here to see home much gold i can actually get out of them. I live in the country in the sticks and Ive ordered so much lab equipment this week off amazon I'm pretty sure they are going to think im aetting up a meth lab. But i have the confidence now to really give it a try. I've been thinking about trying for some time and ive been buying up recycled gold when i can get it super cheap on ebay. I'd be happy if i got a 10% return on the gold 20 grams off of 2000 grams id be happy it would at least pay for the equipment and maybe next batch will turn a profit. I also won an order of 0.87 pounds of 24k gold flake. I shouldnt have to do anything to that correct? Id hatecto melt it down to a bar and it have some impurities in it. I'm new to all this so im not exactly sure these first few time will definitely be experiments and hopefully i get it right.

Absolutely fantastic demo. Superb. The only mistake I believe you made is: When you made the premix AR you went 4:1 HCL to Nitric. At 25:45 you say the 50 ml leftover AR probably contains 8 ml nitric. No, I say 10-12 ml nitric. Then, on the second redissolve where you've combined the two batches and are "reusing" the leftover premix AR, you calc that you'll need 36 ml Nitric. I agree. You start by adding 15 ml new nitric over and above the premix...then just a bit more, in single ml doses. Be that as it may....right or wrong on the math, because you are stingy with your nitric and only add it in the small increments, you made your main point *a second time*. Terrific video, excellent, can't say enough good things about your technique.

The 4 to 1 ratio is for using vacuum distilled ( 90 % nitric acid ) as per Hoke's book. The 3 to 1 nitric is for the 68% nitric . So check your strengths before mixing.
@sreetips5 жыл бұрын
You should never premix aqua regia. I can dissolve a troy once of pure gold in 200ml HCl and 20ml 68% nitric. That's 10 to 1 ratio. Mixing (4 to 1) or (3 to 1) just isn't done like that any more. That's way too much nitric. It wastes chemicals and guarantees that there will be problems with excess nitric during precipitation.

@sreetips6 жыл бұрын
A single refining should get the gold to about 995 with silver chloride being the main contaminant. You can tell that silver is in the gold solution by the cloudiness of the solution after the first refining. If you look closely at the liquid after the second refining (dissolving) you'll see that the filtered solution is crystal clear with no traces of cloudiness. I like to call it clear and bright. You can read a news paper through it. This second refining really cleans the gold up nicely. Gets it to three nines just about every time. This is the reason I always do at least two refinings, to get the gold purity to the industry standard of 999. If it's still cloudy after the second refining, I'll do a third refining. They test my gold with an XRF. It ALWAYS assays at three nines fine, every time.
