Development of Eco-friendly process for the recovery of Lead from lead battery scrap in small scale sector

Abstract

The lead battery scrap mainly constitutes of oxides and sulphates of lead. In Present invesligation an attempt has been made fir better recovery of metallic lead from waste battery scrap after its necessarv treatment. A mini cupola furnace along with comprehensive pollution control system has been developed at IVML to smelt about 200 Kg of lead battery scrap per hour. Simpliied design has been developed for, fabric, filter to arrest fine purticulales of lead and impingement scrubber to absorb the oxides of sulphur as well as arrest the particulates of lead. The emission of lead was brought down < 10 mg/m3 and that of S02 < 300 mg/m3 as prescribed by Central Pollution Control Board, India and the recovery of lead was beyond 86.5%. This eco - friendly process is extrem-ely suitable in small scale sector.
