Effect on Electrochemical Properties for Calcium Ions in Silica-Sphalerite-Mixture (Silica: Sphalerite =4:1) Systems

Abstract:

There is a remarkable interaction when fine particles adsorbed calcium ions in Silica-Sphalerite-Mixture (Silica:Sphalerite =4:1) systems, it is not conducive to mineral flotation. The key is how to reduce or eliminate calcium ions. This paper focuses on the changes of Zeta potential and Zeta potential distribution (ZPD) with the single minerals and complex mineral (silica / sphalerite = 4:1) in different concentrations of calcium ions, and interaction of particles was analyzed by Zeta potential and ZPD.
