Sustainable Mining and Metallurgy

Waste lead-acid batteries contain lead, waste sulfuric acid and other harmful substances, which are hazardous wastes. If improperly disposed, they will cause pollution to the environment. Therefore, harmless disposal and comprehensive recovery are needed. This paper introduced the recovery process of lead-acid battery. On the basis of comparing various lead paste recovery processes, the advantages of oxygen-enriched side-blown bath smelting process for treating waste lead-acid battery were summarized. Taking a recycled lead recovery practice as an example, the process design, key points and parameters of oxygen-enriched side-blown bath smelting process for treating waste lead-acid battery were reviewed and summarized, which provides reference for factory design and technology upgrading of domestic recycled lead industry.
