i was wondering about two things really
1. Im wondering what the best way to precipitate Au out of a AP stock pot, if some one could send a link or tell me that would be great
2. has anyone ever tried to dissolve Kovar pins in AP? and what was the results

keep using your Acid Peroxide solution, the copper in the material will cement any gold if it is in solution.

Acid peroxide will dissolve the kovar, if you add a Whole lot of iron the solution would change this copper chloride solution into an iron chloride solution.
