Industrially, silver is usually a byproduct of processes whose main object is the extraction of another metal such as copper, lead, and zinc. So called "anode slimes" from the electrolytic purification of copper contain silver and a somewhat involved process is finished by an electrolysis of a nitrate solution containing silver.Get Price

gold, silver, copper, tin, lead, and iron. Gold and silver were too soft to be useful for much except decoration. Copper could be hardened by ham-mering or forging and was therefore useful as a tool but had little value as a weapon. Bronze, developed by alloying copper with tin, had use-ful strengths, could be hardened by forging, andGet Price
The higher concentrations of silver in solutions, brought about from upstream process improvements, have made it economically viable to use electrowinning to recover silver. To process high-grade silver-bearing pregnant solutions to pure silver concentrates, electrowinning is best performed using Gekko's innovative electrowinning cell.Get Price
