LEAD INDUSTRY PROFILE In the case of leadzinc ores, the metals are usually separated in a twostage 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
