Silver Ore The Mining Processes that Transform Ore into

Dec 18, 2016&0183&32When 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.
