Copper bars mixed 50 50 with bronze pins?
What do you mean? Also how do you know when the solution is used up and how do you process it afterwards?
I melt equal amounts of low grade bronze pins with equal amounts of copper and pour it into “bars”. They end up about 1/2 inch in diameter and almost 4 inches long. I use an old corn bread pan that shapes them like tiny ears of corn. It was handy, cost me nothing and it is cast iron.

I use the solution until it quit’s working or slows down considerably. This is one of those “make do” methods I seem to mention more these days. I don’t have time or space for a gold stripping cell these days plus I do very little electronic stuff now as well. This method fills a spot that allows me to do favors in return for better materials at times. And you can run the solution from your waste stream in it as well and get more use from already dirty acids.
