froth and floatation process

Froth Floatation Process - iCBSE

A strong current of air is blown through the suspension, producing a heavy froth or foam on the surface.The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to the surface by films of oil The froth is skimmed off, the gangue settles down on the bottom or remains underneath the froth.By this floatation method it is possible to concentrate over 90% of a

Flotation Process - an overview ScienceDirect Topics

The froth flotation process is more than a century old and was developed over a long period of time [8]. It takes advantage of the surface chemistry of fine particles—if one particle’s surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to the air bubbles and float ...

The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. The ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry. A Collector which acts as a surfactant chemical is added to the slurry.

What is the role of depressant in froth floatation

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.

2016-3-8  Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.
