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

MINING AND PROCESSING : Lead is known to naturally occur in free form in nature, but is generally obtained from the ores galena(PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4). It is never considered to be a rare element even though it makes up only about 0.0013% of the earth's crust since it is easily mined and refined.
