Sustainable Mining and Metallurgy

This paper introduced a three furnaces process of double side-blown furnaces and fuming furnace for treating lead-containing raw materials from waste battery disassembly and primary ore mixture containing various valuable metals. From the aspects of material and cost, the traditional three furnaces process of bottom blown oxidation furnace-side blown reduction furnace-fuming furnace and the three furnaces process of double side-blown furnaces-fuming furnace were compared, and the technical advantages of side blown oxidation furnace and the process control in production were explored. The side-blown furnace is more suitable for processing mixed materials. When processing lead-containing mixed materials, the side-blowing furnace will not affect the production of long furnace knots, and does not need to change the oxygen lance regularly, which improves the actual production operation rate. In industrial production, the three furnaces process of double side-blown furnaces-fuming furnace can improve the economic benefits of enterprises while recycling waste lead-acid batteries, and has high environmental protection promotion value.
