So i bought this item on ebay today, and i wanted to ask a couple of questions; i also bought gold plated beads on amazon, and some gold plated jewelry to have different things to experiment on.
First of all, how much gold you guys thing is in the ingot, i am expecting around a gram hopefully, so it at least covers the buying price.
second and most important, i wanted to get recommendations on what chemical processes should i use to refine it fully, and also extract the copper if its not too much of a hassle, i was thinking on using hydrochloric acid with sodium hypochlorite to purify the bar.
Also what do you guys recommend to do with the plated items, i was thinking on doing HCl with hydrogen peroxide, and just take the gold foil, but for the base jewelry i do not know what the base metals would be, so would HCl dissolve most base metals used in jewelry??
Thank you very much form your patience!!! it is very much appreciated <3
