Lead Mining – Concentration process, flotation, filtering ...

Lead is extracted from ores dug from under-ground mines. Lead is also found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by- product of these other more valuable metals. Extracting the lead materials from the ore is a tedious process. First the lead ore is ground into small salt-like particles.

How Is Lead Mined? - Reference

Apr 03, 2020  Lead is commonly found in deposits with other minerals, such as silver, zinc or copper. 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.

Lead processing - Mining and concentrating Britannica

Lead processing - Lead processing - Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral ...
