How do you separate gold silver and copper?

2020-3-14 · How do you separate gold silver and copper? Add some copper and silver to the crucible before melting the gold in the furnace. Remove the crucible and allow the metallic mixture to cool and harden. Pour nitric acid over the metallic mixture. The acid will dissolve the silver and any base metals, and pure gold will remain.
