Silver mining - Wikipedia

Silver mining is the extraction of the precious metal silver from the Earth through excavation (i.e., mining). Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag2S), chlorargyrite ("horn silver," AgCl), and galena (a leadore often containing significant amounts of silver). As silver is often found in conjunction with these or alloyed with other metals such as gold, it usually must
