The relationship between anion distribution in process ...

Aug 01, 2020  The flotation results pointed out that anion at higher valence in the process water tends to have more significant influences on lowering the content of SiO 2 in concentrate. This could be attributed to the zeta potential modification on the mineral surfaces by the adsorption of these anions, strengthening the interactions between minerals and ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

The flotation process is governed by a complex phenomenon occurring on the surface of mineral particles and air bubbles formed in the water phase. From the practical point of view, the hydrophobicity and bubble mineralization are perhaps the two most important factors in flotation and govern the system kinetics and selectivity of flotation.
