2016-6-22  Argentite, which is a sulphide ore, is the chief source of silver. It is extracted by the process of leaching with a dilute solution of sodium cyanide. Silver dissolves and forms a complex, argentocyanide. It is further treated with scrap zinc, which displaces silver from the complex. This is called displacement method or hydrometallurgy.
