Introduction to Mineral Processing - Chevron Phillips Chemical

The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc .

Also, the recovery of silver minerals occurring in a lead, zinc sulfide ore is efficiently accomplished using Flowsheet #2. The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate.

Lead - Essential Chemical Industry

The process is carried out in a series of tanks. As the lead and zinc minerals are less readily wetted than the gangue, they adhere to the air bubbles which are carried to the surface. The rock particles sink and the lead and zinc ores are skimmed off. Then the lead ore is separated from the zinc ore.
