    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 ("horn silver," Ag Cl ), and galena (a lead ore often containing significant amounts of silver).
