ABSTRACT

The interactions among fine particles are unavoidable in solutions, and the strong particle interactions have a negative impact on mineral separations. How to reduce and prevent the agglomeration of particles is one of the important chal-lenges facing production and research. The interactions of sphalerite and silica particles were studied with variation of calcium ions solutions. Zeta potential measurement and a novel Zeta potential distribution (ZPD) measurement method were used in this paper. The phenomena of mineral coagulation and absorption of flotation reagent were analyzed in solutions of different pH and calcium ion concentration.
