Lead Ash from Lead Smelters (Pb 40%)

The secondary production of Lead begins with the recovery of old scrap from worn-out, damaged, or obsolete products and with new scrap. The chief source of old scrap is Lead-acid batteries; other sources include cable coverings, pipe, sheet, and other Lead-bearing metals. Solder, a tin-based Lead alloy, may be recovered from the processing of circuit boards for use as Lead charge.
