Electrolytic Silver Recovery - Industrial Wastes
2021-8-11 Electrolysis, or more specifically electrowinning, is the most widely used and universally applicable method for silver recovery in the photoprocessing industry. An electrolytic silverrecovery cell consists of a cathode and an anode. Oxidation occurs at the anode (positive electrode) and reduction at the cathode (negative electrode).

Electrolytic cell ? Gold Refining Metal Extraction Forum
2011-2-5 Silver is soluble in concentrated sulfuric. Depending on the strength of the sulfuric, silver could be both in solution and as a silver sulfate solid. If you're using paper filters, you couldn't directly filter the sulfuric anyhow. I know of several ways to strip silver from copper base, but none of them are practical.
