Froth Floatation Process ... In this method, powdered ore is put in a tank full of ... which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth. The gangue particles being heavier remain behind at the bottom of water tank. The froth is separated and concentrated sulphide ore is obtained from it.

Talk:Froth flotation - Wikipedia

I think "flotation" should remain a separate keyword and not integrated into "froth flotation". In the paper industry, flotation is the key process in the recycling process for recovered paper, the deinking process. Nobody uses the term "froth flotation". I might find the time to suggest updates for both the keywords flotation and deinking.

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.

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.
