Lead processing Refining Britannica

Lead processing Lead processing Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely usedget price
