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

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.
