Embark on an extraordinary journey into the world of precious metal refinement as we showcase the intricate process of smelting and refining gold and silver. In this captivating KZfaq video, we delve into the age-old techniques of smelting and cupelling, complemented by modern wet chemistry and nitric acid methods, to extract pure gold and silver from a mixed metal bullion.
Watch in awe as the transformation begins with the smelting process, where the mixed metal bullion is heated to high temperatures, allowing us to separate the gold and silver from other base metals. Witness the artistry of cupelling, as we further purify the metals to eliminate any remaining impurities, leaving us with pristine gold and silver beads.
Delve into the realm of wet chemistry techniques, where precise chemical reactions are employed to ensure the utmost purity of the precious metals. Marvel at the process of using nitric acid to dissolve any remaining impurities, refining the metals to their highest grade.
Throughout the video, we share insights into the delicate balance of ancient and modern methodologies, crafting an exquisite symphony of science and artistry to reveal the gleaming essence of gold and silver. Our meticulous attention to detail and dedication to the craft allow us to obtain the highest-quality precious metals, ready to be transformed into valuable and sought-after pieces.
Whether you're a passionate precious metal enthusiast, a connoisseur of metallurgical processes, or simply captivated by the magic of alchemy, this video promises to captivate and educate. Join us on this mesmerizing journey as we extract, refine, and unveil the purest forms of gold and silver, a testament to the beauty and value of these timeless treasures.

Sreetips does another refining by dissolving the gold in Aqua Regia and precipitating it back out prior to melting. I'm not sure if this one is even two 9s fine without the AR bath

When melting the alloy inquart stir with a carbon or quartz stir rod to mix thoroughly. Gives a near perfect alloy every time. Check out the "flame polishing" technique Jason it's what the mints use. Nice mirror finish. Thanks for sharing

Man, I knew I should have payed attention in chemistry class lol. So cool to see how all the different elements react with each other and burn off what you don't need. Cool video, thank you Jason!

@redbaronrefining5322 11 ай бұрын

Friendly tip Jason; When using nitric, keep your heat on low, add nitric, and once reaction slows down, then bring the temp up. There are 2 main things you’re doing that is wasting the nitric. 1: boiling the nitric will cause it to evaporate off/be consumed 2: not using a watch glass (cover) on top of the beaker causes the nitric to burn off easier. When you use a watch glass, not only can you monitor fume production to help you with determining if nitric is working still, you also get a nice distillation effect that causes the nitric acid to pool up into droplets and finally fall back into solution so you “recycle” the nitric and that same acid goes a lot longer. You can always boil the gold in some nitric if you want to clean it up a bit after the melt, although going straight to agua Regia after the inquarting process is best. Great work regardless, it’s a bit of a tricky process that takes time to get down to a science :)

@hpdepasse5997 11 ай бұрын

your gold look nice finaly, but you may try with aqua regia : muriatic acid + a few ml of nitric to dissolve the gold only, filtered, then precipitating it.

@Michael-rg7mx 11 ай бұрын

I wore a half mask most of my career. Check with your supplier or read the directions. My cartridges for acid vapor were only good for 1 day. He told me if I'm using it intermittently I could stretch it to 8 hours of use if I took them off immediately. Taped over both sides and sealed them in a freezer bag with desiccant. Write on the bag how long it was used each time. They suck impurities right out of the air as long as they're exposed. You don't want to end up on oxygen at 50. Change those filters.

@CuttinEJ 11 ай бұрын

When you inquart you really need to manually mix the metals thoroughly to produce a homogeneous alloy. To finish the refining process you need to dissolve the gold in HCl and Nitric, then filter until the solution is crystal clear, then precipitate. Precipitation can be done by any of several methods, but SMB is the easiest. After precipitation the gold powder needs to be thoroughly washed and then you can melt it in a properly glazed dish.

@B0BBYL33J0RD4N 11 ай бұрын

When you were asking about the mix, if you were having an issue with the non-disolving stuff, just add more silver In terms of silver efficiency, it is better to use the exact right ratio. In terms of best purity, use an abundance of silver, as a well mixed alloy can still have pockets of high gold density. If you use more silver, it might mean the acid has to eat through 4 molecules of silver instead of 3 per gold molecule, but the more dense pockets will actually clean up better. I think it means the difference in 99.9 and 99.999% but

@Alondro77 11 ай бұрын

Yeah, you always want to put a little excess silver when inquarting. It doesn't hurt the process and compensates if your initial material is higher in gold than estimated.

@johannesdesloper8434 11 ай бұрын

I watch a lot of Sreetips. He usually does 75% x 95% of Silver to keep the inquarted shot in pieces in the Nitric boils and not end up with a Gold powder that is hard to spearate from the liquid. He stirs the inquarted Gold with a carbon rod to get a homogenous alloy. He usually does 5 Nitric boils or so. If you add a drip of Hydrochloric to a small amount of Nitric boil you can check for Silver. Silvernitrate will form white SilverChloride that is insoluable. Very sensitive test. Good luck and be carefull!

If you smash the Cu pipe it works out better than as the pipe just going into the stock pot. Ag and anything else will end up stuck in the pipe becomes a mess to get it back out like that, the thicker you can make the Cu in the form of plate without any openings the better it will cement things out of solution any Au that was taken away by the NO3 in nano particles as a colloidal stuck in suspension will also cement to the Cu and gets caught up in the mess of Ag cementing out and has to be worked again in order to recover it. You did a great job showing how to get started with the process of hydrometallurgy and the mathematical breakdown was easy to understand what you where talking about in the alloys composition. Thank you for the video very useful information and the showing of each deposit type is different and will require you to make some changes as needed for the recovery.
