Production of lead for further use as metal.
Gaining the metalThe proportion lead in the battery – the mesh metal and the lead paste – is around 60 percent. The mesh metal and the paste are separated in the processing plant.
The paste can, on the one hand, be desulphurised and, on the other hand, processed into lead and sulphuric acid in a primary lead smelter. The mesh metal and the desulphurised paste are smelted in the short rotary furnaces of the secondary smelters and reduced to bullion.
Approximately 70 to 80 percent of the lead is used for automotive and industrial batteries. 20 to 30 percent goes to other uses, for example into radiation protection, as roofing material, optical glass, lead crystal or cable sheathing. (HS)
