Effect of Serpentine on Flotation of Ascharite

doi:10.12068/j.issn.1005-3026.2017.08.019

Abstract

Abstract: Aiming at the problem that serpentine can deteriorate the flotation environment of ascharite， the effects of different sizes of serpentine and minerals ratio on the flotation efficiency of ascharite were investigated by flotation experiments. The results showed that the interaction between serpentine and ascharite particles can occur easily during flotation process. With the increase of content and the decrease of particle size for serpentine，the recovery of ascharite decreases gradually. Besides， fine serpentine has more prominent effect on flotation recovery of ascharite and can lower the recovery of ascharite more remarkably. The mechanism of mineral particles interaction was also studied through zeta potential analysis and DLVO theory calculation. The result indicated that minerals surfaces with opposite charges are the basic reason of the interaction between mineral particles.

Key words: serpentine, ascharite, flotation, DLVO theory
