explain froth floatation process? Yahoo Answers

Dec 16, 2006 Best Answer: Froth Flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) orebodies economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.

The flotation process was developed on a commercial scale early in the 20th century to

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.
