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.

Pilot Scale Froth Flotation Studies To Upgrade Nigerian

pre-concentration of iron ore by gravity or magnetic methods. The flotation method commonly applied is the one based on cationic flotation of silica and silicates, that is, reverse flotation [5]. The reagents required for froth flotation are collectors, frothers and regulators, such as activators and depressants.

Celanese

In these cases, the initial ore could contain between 0.1-0.5% of the desired metal or mineral and following the flotation process the grade can increase to 20-25%. However, the froth flotation process is also used to extract coal, iron, potassium chloride, phosphates, and – in the paper recycling industry – for deinking paper fibers.

Froth Flotation and its Application to Concentration of

Froth flotation is a process used to separate minerals, suspended in liquids, by attaching them to gas bubbles to provide selective levitation of the solid particles. It is most extensively used process for the separation of chemi-cally similar minerals, and to concentrate ores for econo-mical smelting. Flotation is a selective process and can be used to achieve separation from complex ores
