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.

From the perspective of recovery of copper (Cu), gold (Au), and silver (Ag); the thermodynamic analysis predicted that the process conditions at temperature of 1300 °C and oxygen partial pressure (pO 2) of 10–8 atm are suitable for PCB processing through secondary copper smelting route. Under these conditions, no solid phases were predicted to form when the PCB addition is below 50 wt%.
