Lead is extracted from ores dug from underground mines. Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjuction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable [//]Lead is extracted from ores dug from underground mines.

The Parkes process is a pyrometallurgical industrial process for removing silver from lead during the production of bullion. It is an example of liquid–liquid extraction. The process takes advantage of two liquidstate properties of zinc. The first is that zinc is immiscible with lead, and the other is that silver is 3000 times more [//]The Parkes process is a pyrometallurgical industrial process for removing silver from lead during the production of bullion.

While recovering zinc through hydrometallurgical process, lead and silver were separated out as commercially poor grade LeadSilver Concentrate (LGLC), which was stored as inventory. If the utilisation of these wastes can be enhanced, it would result in greater environmental sustainability and improved recovery of ore.[//]While recovering zinc through hydrometallurgical process, lead and silver were separated out as commercially poor grade LeadSilver Concentrate (LGLC), which was stored as inventory.
