EMERGING TECHNOLOGY BULLETIN: RECLAMATION OF LEAD FROM SUPERFUND WASTE MATERIAL USING SECONDARY LEAD SMELTERS
Paff, S. EMERGING TECHNOLOGY BULLETIN: RECLAMATION OF LEAD FROM SUPERFUND WASTE MATERIAL USING SECONDARY LEAD SMELTERS. EPA/540/F-94/510, 1994.
This process involves incorporating lead-contaminated Superfund waste with the regular feed to a secondary lead smelter. Since secondary lead smelters already recover lead from recycled automobile batteries, it seems likely that this technology could be used to treat waste from lead-acid battery contaminated Superfund sites. Such sites are very widespread and constitute a significant problem in site remediation. The overall process involves acquiring the waste material, transporting it to a secondary smelter, blending it with typical feeds, and smelting it to reclaim usable lead. A schematic of this process is shown in Figure 1.
