Study on the interaction in Silica-Sphalerite-Mixture (Silica:Sphalerite =4:1)-Calcium carbonate systems

摘要

There is a remarkable interaction when fine particles adsorbed calcium ions in sphalerite/silica system, it is not conducive to mineral flotation. The key is to how to reduce or eliminate calcium ions. The calcium ions concentration is decreased significantly if the accumulation of gypsum is converted to calcium carbonate in the circulating water. This paper focuses on Zeta potential and Zeta potential distribution (ZPD) with single minerals and Mixture (silica/sphalerite=4:1) in calcium carbonate solution, and the interactions of the sphalerite/silica particles was analyzed.
