Froth Floatation Used In

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.

FROTH FLOATATION PROCESS - This method is used when a higher ore contains impurities with higher density. This method is used for the concentration of Sulphide ores (e.g.: Copper pyrites, iron pyrites, Galena, Zinc blende etc.,)

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. This happens because NaCN reacts with ZnS to form Na 2 [Zn(CN) 4]. 4 NaCN ...

FLOTATION

In the minerals industry, selective froth flotation is used to concentrate specific species of particles in a finely ground ore. "Flotation" is a generic term for a number of processes known as "adsorptive bubble techniques", Lemlich (1972); these are classified into foaming and nonfoaming separation methods. Foaming methods require the addition of surfactants to generate a relatively stable ...
