extraction of ore of gold

Silver mining

Silver mining is the resource extraction of silver by mining. Silver is found in native form very rarely as nuggets, but more usually combined with sulfur , arsenic , antimony , or chlorine and in various ores such as argentite (Ag 2 S ), chlorargyrite (quot;horn silver,quot; Ag Cl ), and galena (a lead ore often containing significant amounts of silver).
