Review of ASARCO El Paso Smelting Processes
Review of ASARCO El Paso Smelting Processes 21 2 2. Smelting Processes at the El Paso Smelter Lead, copper, zinc and cadmium were smelted at various times in the El Paso smelter during its operation. Although various metals were smelted, the general smelting processes were similar since pyrometallurgical processes (addition of heat and oxygen)...

Secondary Lead Smelters Envitech
Secondary Lead Smelters. The primary source of scrap material is lead acid batteries. The lead is separated from the battery casings in a battery breaking process. The lead is then smelted in furnaces which can include blast, reverberatory (reverb), rotary, or electric arc furnaces. The smelted lead is then further refined into a finished lead product for commercial use....
