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 ...

Besides the ore itself, only a few raw materials are necessary for the refining of lead. The ore concentrating process requires pine oil, alum, lime, and xanthate. Limestone or iron ore is added to the lead ore during the roasting process. Coke, a coal distillate, is used to further heat the ore. The Manufacturing Process Mining the ore 1 The first step in retrieving lead-bearing ore is to ...

Ore Refining - an overview ScienceDirect Topics

Mining operations and refining ores for the manufacturing process will result in environmental issues and impacts; these include high energy use, physical disturbance of the landscape and pollution from toxic emissions, which may affect land, water and air. There is scope to use recycled content within many insulation products, which would reduce the impacts at this stage.
