I have 900 grams of sterling silver and I am going to (try to) refine about 1/2 of it by disolving in Nitric (when it arrives) then using the copper percipitation. I will be using the watch glass to cover the beaker and I will measure everything that goes in and comes out. I'm real interested in seeing how much nitric acid is going to be needed. I have probably 50 lbs of copper laying around here.
I'm going to store and keep the liquid after the percipitation in gallon water bottles. I will test to make sure the acid is depleted and that no more silver is left. When I get finished I'll probably drop some more copper in to make sure all the silver is depleted. Will this solution be copper nitrate? What uses might there be for it down the road besides killing roots in a sewer line?
This 1/2 will be melted and poured into 3 oz bars and I might frame them and hang them on the wall. The remainder of the sterling will be retained until such time that i can get some scrap AU.
I was concerned about cutting all that sterling up then I remembered that I have some Milwaukee electric metal shears!
