Process for using lead battery scrap. Verfahren zum Verarbeiten von Bleiakkumulatorenschrott

Abstract

The process for using lead battery scrap is such that it leads to an increase of lead metal without the use of fluxes for forming the melt. According to the invention, the battery scrap is broken up, dangerous parts (organic substances containing chlorine) are removed and large pieces of lead (pole bridges, grids, contact pins) are sorted out. The remainder is chopped up into pieces less than 10 mm in size. The small pieces are melted by the suspension melting process at a temperature of 1300 to 1500/sup 0/C in an oxidising atmosphere (air or oxygen) without using any fuel. As the small pieces contain parts of the battery case (= organic substances free of chlorine), they burn in air generating heat, which is then used to melt the sulphate oxide lead compounds. The previously sorted large lead parts are then added to the lead oxide melt. Finally, the lead oxide is reduced to lead metal with coke in a furnace. After the reduction of lead oxide to lead, less than 0.2% of the initial lead content in the battery scrap being processed is lost in the dumped slag.
