Lead smelting20.5.1. Reverberatory furnace smelting. The reverberatory furnace and blast furnace or electric furnace combination is seen primarily in the USA. It is a two-stage oxidation-slag reduction process in which the charge consists of battery scrap, lead scrap, drosses and internally recycled dust combined with coke.

Lead and zinc can be produced pyrometal- lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet- allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin- tering, into a primary smelter. Lead concentra- tions can be 50–70%, and the sulfur content of sulfidic ...

A more efficient method for treating battery scrap appears to be smelting in a blast furnace. This method is the most popular, for the direct product is antimonial lead. However, both methods produce copious quantities of SO2. Large quantities of SO2 are produced because of the large amounts of PbSO4 and H2SO4 found in the scrap battery.

Huang et al. (2012) studied sulfur-fixing reduction smelting of scrap lead paste in fused salt at low temperature. Zinc oxide (ZnO) is used as sulfur fixing agent to reduce lead paste into crude lead in the molten salt of Na 2 CO 3 at 800 ° C–900 ° C. This process reduces SO 2 generation and emissions, but consumes more Na 2 CO 3.
