Froth Flotation in Mineral Processing MINERALLURGy

Froth floatation is a method of separation of minerals or particles, by taking advantage of the differences between their superficial proprieties in a water solution. It is a mineral processing technology that involves three phases, solid, liquid, and froth. Solid refers to particles bearing minerals.

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.

Flotation Froth an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
