Silver can be refined through electrolysis, using anodes made up of crude silver and gold: approximately 60% silver, 30% gold, and the remaining 10% as base metals. The anodes are made by charging silver and gold bullion into a furnace, the same furnace that is used for melting fine silver and gold to be cast into bars.
