LEAD ZINC EXTRACTION PROCESSES

LEAD ZINC EXTRACTION PROCESSES

are used for production of lead zinc depending on the type of raw material used as a charge. In the pyrometallurgical process ore concentrate containing lead zinc or both is fed in some cases after sintering into a primary smelter. Lead concentrations can be 50-70 and the sulfur content of sulfidic ores is in the range of 15-20 .

LEAD INDUSTRY PROFILE

LEAD INDUSTRY PROFILE In the case of lead-zinc ores the metals are usually separated in a two-stage process. First the zinc sulphide is depressed while the lead sulphide is floated off and removed. In a separate stage further additions are made to activate the zinc ore and it is floated off. The froths are then broken down by water sprays and the
