mineral processing of silver

Silver: Mineral information, data and localities.

Silver is used in jewelry, tableware, coins, scientific equipment and in photographic processes. Silver tarnishes black with a surface layer of acanthite (silver sulphide), especially when placed in proximity to sulphurous compounds. It is primarily found as a constituent of hydrothermal veins. It is often found associated with copper.
