Refining Gold With Copperas (Iron Sulfate)
Hey there, welcome to my channel! In this video, I'll be demonstrating the process of dissolving dirty gold powder using aqua regia and then precipitating out the gold using sulfamic acid to neutralize any excess nitric acid, followed by using copperas to further purify the gold powder. I'll walk you through each step of the process, so you can see how to refine gold at home. If you're interested in gold refining or just enjoy chemical experiments, be sure to watch more of my videos! Don't forget to like, comment, and subscribe for more content. Thanks for watching!
