What's the Function of Flotation Froth in the Froth .

Flotation reagent is also an essential item in the froth flotation process. The purpose of reagent is to strengthen the stability of mineralized froth in the froth flotation process, allow air dispersion and froth formation independently, increase the hydrophobicity of natural mineral surface and increase the separability of hydrophilic and hydrophobic particles.「 new design mineral flotation cells」Flotation system is based around a group of 6 float cells arranged in a circular tank, each individual cell fitted with impellers, air spargers and froth launders. Host of benefits in the design; better mixing in slurry applications, resulting in greater efficiency for reactions and a greater uniformity within the tank.Flotation - ScienceDirect1/1/2016· The flotation technique to separate minerals from their gangue contents suspended in a fluid (mainly water) depends on the interfacial tension between hydrophilic/hydrophobic mineral surfaces and their environment. The physico-chemical forces involved are explained in this chapter.Flotation Process - an overview | ScienceDirect TopicsThe linear structure of the flotation cells has a large surface area, which has reject separation and fiber loss. This flotation cell design also contributes to high sludge consistency (less water in the sludge) by ensuring smooth drainage of froth (Aksela, 2008).
