Lead processing Refining Britannica

Lead processing Lead processing Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used

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

Refining of lead from lead battery recycling STC Italy

The pyrometallurgical Lead refining process is one of the most important procedures of lead battery recycling. This process is also known as “Softening of Lead” because the metal is softened after the removal of some impurities which are present in the raw lead coming from lead battery recycling.It would be more correct to call only the process of antimony, arsenic and tin removing
