Precious Element Analysis in Lead and Zinc
Lead and zinc can be produced pyrometallurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 50-70%, and the sulfur content of sulfidic ores is in

How lead is made - material, used, processing,
Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver. Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries. Besides the ore itself, only a few raw materials are necessary for the refining of lead. The ore concentrating process requires pine oil, alum, lime, and xanthate

How Is Lead Mined? | Reference
Once the lead ore is brought to the surface, it goes through a series of refining processes that separate out the different metals contained in the ore. For example, U.S. mines in Alaska and Missouri are zinc and lead operations. These mining operations are highly mechanized, because the work is so dangerous. The smelting operations themselves are also extremely dangerous, because lead is
