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.

Froth Flotation Process - Detailed Explanation With Diagrams
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by ...
What's the Function of Flotation Froth in the Froth Flotation
Froth plays a very important role in the froth flotation process. Because of these froth, ore particles or mineral powder can adhere to the sticky froth, then the froth carries these particles out of the pulp, then reaches washing surfaces to remove ore particles, thus achieving froth flotation process and obtainning the concentrate.
Separation of plastics by froth flotation. The role of size
Froth flotation is one of these techniques, which is based on hydrophobicity differences between particles. Unlike minerals, most of the plastics are naturally hydrophobic, thus requiring the addition of chemicals that promote the selective wettability of one of its components, for a flotation separation.
