Lead Zinc Separation by Flotation - Froth Flotation ...

Sphalerite generally does not float well with xanthate collectors especially short xanthate collectors. So to be able to float sphalerite, it should be activated by a metal at a certain PH. Some of the metals that can do the job are copper and lead. At a pH between 8-9 lead can activate sphalerite to cause it flotation.

Lead and Zinc - US Department of Energy

Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

Flotation Collectors - Mineral Processing & Metallurgy

Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman's term 'afraid of water' or 'water hating' as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car. After wax (or hydrophobic agent) is adhered to the surface, that surface with see water pearl-away.
