  • 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 ...

  • Lead smelting - Wikipedia

    Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.
