Silver mining - Wikipedia

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 (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver). As silver is often found in conjunction with ...

Silver processing Britannica

The remaining lead-gold-silver residue is treated by cupellation, a process in which the residue is heated to a high temperature (about 800 °C, or 1,450 °F) under strongly oxidizing conditions. The noble silver and gold remain in the elemental form, while the lead oxidizes and is removed. The gold and silver alloy thus produced is refined by the Moebius or Thum Balbach process. The residue ...
