It's principle The flotation process, based on the properties of the surface chemistry of minerals. Chemical reagents (collectors reagent, frother, etc.) and air are fed into the pulp, particles bearing minerals are collected at the air-liquid interface, adhere to air bubbles, and carried out to the surface forming a three-component froth, which goes for further processing (cleaning, thickening, filtration, …

Froth flotation is a process for selectively separating hydrophobic materials from hydrophobic. In some cases, for example, sulphides ores of copper, zinc and lead concentration is brought by this method.In this method, the advantage is taken of the preferential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or turpentine oil.

N a C N forms a layer of the complex N a 2 [Z n (C N) 4 ] on the surface of Z n S and prevents it from forming a froth. Thus, it acts as a depressant. However, N a C N does not prevent P b S from forming froth and allows it to come with froth.

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.

During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.
