[PDF] Electrolytic method for recovery of lead from scrap,
Prior work at the Bureau of Mines resulted in the successful development of a bench-scale, combination electrorefining-electrowinning method for recycling the lead from scrap batteries using waste fluosilicic acid (H/sub 2/SiF/sub 6/) as electrolyte. This paper describes larger scale experiments. Anodes cast from scrap battery lead were electrorefined in a 20-L multielectrodeEP0238714A1 - Electrolytic recovery of lead from scrap,,Lead is recovered from lead-containing scrap metal in an electrolytic process employing an aqueous solution of C 1-4 alkanesulfonic acid as the electrolyte at a high concentration, scrap lead as the anode, and an electroconductive cathode, impressing an electromotive force across the solution between the electrodes to provide a specified steady-state concentration of leadElectrolytic recovery of lead from scrap,A process for the electrolytic recovery of scrap lead which comprises utilizing an aqueous c 1-4 alkanesulfonic acid as the electrolyte at a concentration of about 15 to about 70% based on the weight of the electrolyte, scrap lead as the anode and an electroconductive material as the cathode, impressing an electromotive force across said electrolyte between the electrodesElectrolytic Metal Recovery | Products Finishing,01-08-2004· Electrolytic recovery in waste streams (also known as electrowinning) is a very good method to recover those metals and minimize further treatment. It essentially involves removal of metal ions from a plating solution and/or associated rinse by plating them out. Generally speaking, this process has a couple parameters that are not requirements,E-Scrap - Computer Recycling & Electronics Recovery,Electronics Scrap Recovery operators also recycle a variety of scrap metals, waste plastics and other misc. materials procured from the dismantling or stripping down of old or waste electronics.
