Silver Element Extraction Methods Open Pit Underground

The ore containing silver needs to be refined to obtain pure silver as an end product. The silver precipitate obtained previously may contain some impurities and so the impure silver is purified by the electrolytic method. The process requires a block of impure metal to be the anode while a thin strip of pure silver is fetched as cathode.
