Froth flotation : recent trends iime jamshedpur 1998; pp18-41 flotation of sulphide ores - hzl experience vzawar mines udaipur - 313 901 abstract flotation process patented in the year 1906 was originally developed for mineral industry to recover values from high grade tailings of gravity separation plants.
Froth treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separationThere are two different types of hydrocarbons used in froth treatment: a naphtha-based hydrocarbon and a lighter paraffinic solventBoth produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.
The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors specifically xanthates and dithiophosphate collectors that allowed differential flotation of sulfide minerals weinig and carpenter 1937 rabone 1939 richards and locke 1940 taggart 1945.
