The silver used by the ancients was probably obtained by smelting lead sulfide ore, rich in silver (argentiferous galena).

US4670115A - Electrolytic silver refining process and ...

In an electrolytic silver refining process, crude silver is anodically dissolved while refined silver is cathodically deposited and at the accompanying (impurity) metals are selectively extracted from the used (spent) electrolyte and transferred to an aqueous phase. The used electrolyte is enriched in silver and accompanying metals are cathodically deposited and thus removed from the electrolyte.
