Anion Flotation Process

The relationship between anion distribution in process ...

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 collectors.
