The method utilized is called the Parkes process, where the silver is removed from lead and some other types of metal through a liquidtoliquid extraction procedure. Silver can also be extracted from copper and zinc through a similar process in which the silver is purified by a nitrate solution. Another source of silver is refined from gold mines.
