Froth Flotation

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.
