Silver element extraction methods GREAT MINING
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. A mixture of silver nitrate solution is taken as the

Silver mining
Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. As such, most silver produced is refined from sulfide ores such as galena (lead) or chalcopyrite (copper) which contain small amounts of silver. Many of these ores are mined for their value as sulfide ores, and silver is extracted as a valuable by-product, however, some ores are mined explicitly for their silver value. Flotation separation is a key step in this complicated process. Silver mineralizes most commonly as arge
