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
