Silver mining is the extraction of silver from minerals, starting with mining. Because silver is often found in intimate combination with other metals, its extraction requires elaborate technologies. In 2008, ca. 25,900 metric tons were consumed worldwide, most of which came from mining. Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. Specific minerals include argentite (Ag₂S), chlorargyrite ("horn silver," AgCl), polybasite (Ag, Cu)₁₆Sb₂S₁₁), and proustite (Ag₃AsS₃). Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of copper and lead, respectively. Some ores are actually mined explicitly for their silver value vs the silver being a byproduct of other metals. However silver is only found rarely in a native form as nuggets, in placer deposits, and veins. Read more at https://en.wikipedia.org/wiki/Silver_mining
