furnace process to make lead sulfide,lead sulfide ore is converted into lead oxide which is reduced to metallic lead by a continuous process in a blast furnace. refining of blast furnace bullion yields 99.99 pure lead. the relatively low cost easy workability and good environmental resistance of lead have made it in the past an obvious choice for sheathing purposes. however in.copper concentrate analysis by pressed powder method rigaku ,copper ore mined as mainly sulfide ore is usually shipped as concentrate of 20 40 in copper content after processing at the plant near mine site. copper concentrate contains a variety of impurities that are either valuable elements as byproducts, or harmful to quality in copper metal products and hazardous to the environment and human health..
