silver ore and mining extraction process

Process Of Extracting Silver From Ore

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).

Smelting and Roasting Ores to recover gold, silver and ...

2014-6-26 · The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
