Silver Ore - The Mining Processes that Transform …

When silver is found in ores containing copper then the electrolytic refining method is used to extract the silver. The ore is placed in an electrolyte solution with a cathode and an anode. Electricity is then passed through the solution forcing the silver to accumulate around the anode while copper attaches itself on the cathode. This is then collected and leached to remove impurities.
