Lead Smelting
Two-stage smelting. Often the large secondary smelters use a two-stage process to smelt battery scrap. With a limited amount of reduction in the first stage, a 'soft' lead and a high antimonial slag are produced. This process is usually carried out in a reverberatory furnace with capacities exceeding 50 000 tpa.
