Bonsoir, good evening.
I have been getting my feet wet by dissolving my silver scrap (I am a bench jeweller by profession) and recovering the silver, and that all went outstanding well. I have read Hooke's once from start to finish, and keep reading and revisiting things. Ultimately, I don't know if I continue to refine my metals, or just parts, or none, but it's a great experience for a precious metal-guy.
So I was left with my silver cemented out and a nitric solution of copper. Originally, I just wanted to get rid of it, environmentally correct, and dumped scrap iron into it. It sat for a month or two. I changed my mind telling me that it would be a nice exercise to collect the copper as well.
I filtered a good amount of that brown mud that settled, but I am at a loss of what I have at hand now. Reading the forum (and it's posting about that subject) are still over my head, so excuse my stupid questions.
1. If I assume for the moment that I had no idea what I have here in front if me, would I be able to tell if this is copper or iron oxide (rust) ?
2. My intention is to wash the mud a couple of times with HCl to get rid of any Zn, Pb, ... or whatever I have left. Then washing with distilled. Good thinking ?
3. The 'brown soup and mud' (tm) did actually leave a coloration on glass and porcelain I used in the process. It doesn't go away with simple washing under running water. Side question : How to take care of my dishes ? Is tap water "allowed" for household tasks ?
Sorry for the stupidness, I can only hope this helps the next guy on the same road.
