Silver mining is the resource extraction of silver by mining. Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag2S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver).

Silver ores. The most common silver-bearing minerals recovered by flotation are argentiferous galena, native silver, argentite (Ag2S) and tetrahedrite (Cu,Fe,Ag) Sb4S3). Often these minerals float with the base metals such as copper and lead sulphides or are the primary target mineral (tetrahedrite). Aryl (cresylic or phenyl based) and alkyl based ...
