ore is heated to liquefy the mineral, the chalcocide (the oxygen or sulfur) extracted in gaseous or other form, and the resulting metal skimmed off (drossed) or poured off and formed into solid bricks (ingots). Since the target metal is usually present in the beneficiated ore in concentrations significantly less than a few percent, a very largeIn general, the industrial grade of sulphide ore is 4-5%, mixed ore 6-8% and oxidized ore 8-10%. If your lead-zinc ore grade is higher than the above percentage, it will be profitable to processImportant Lead-zinc Ore Processing Knowledge
