Froth floatation
16/6/2013· Froth FloatationPresented By:Gulfam Hussain 2. Introduction Floatation is an extractive process where variousminerals can be selectively extracted. Flotation is a selective process and can be used toachieve specific separations from complex ores. For example, in polymetal ores such as PbZnCu, floatation allows separate extraction of Pb, Cuand Zn.

Froth Flotation | Hazen Research
Froth flotation for separating discrete mineral particles from gangue was developed in the early 1900s and depends upon differences in the surface chemistry of the mineral species involved. We have studied not only the flotation of sulfides, gold ores, iron ores, coal, oil shale, and many other nonmetallics, but also soluble salts, oxides, and some uncommon materials from waste streams.
