The —3/8″ fraction goes by gravity to a Mineral Jig which produces a final jig concentrate from the slimy — 3/8″ mill product This jig due to its selective action saves the fine mineral as well as the coarse siz Very coarse lead minerals if present can be discharged by means of a center draw Research on a cleaner less energy intensive lead extraction process continues a major drawback is that either too much lead is lost as waste or the alternatives result in a high sulfur content in the resulting lead metal Hydrometallurgical extraction in which anodes of impure lead are immersed into an electrolyte and pure lead is deposited
