Froth Flotation of Iron Ores
Jan 02, 2012· With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Froth Treatment Explained | Oil Sands Magazine
Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbonbased gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphthabased hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.

What is the role of depressant in froth floatation process?
In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.
