Title: Flotation Behaviors of Magnesite and Dolomite Using a Mixed Collector
Abstract: Magnesite and its main associated mineral dolomite are with a small floatability difference because of similar crystal structure and surface properties, which results in low flotation recovery of magnesite from dolomite. In order to solve the problem, a new mixed collector of sodium oleate (NaOL) for magnesite was proposed in this paper. The effects of flotation behaviors of magnesite and dolomite were investigated by flotation experiments, and the mineral wettability was characterized by contact angle testing. The results show that the mixed collector could greatly reduce the hydrophobicity of dolomite and improve the floatability difference between magnesite and dolomite. The Gaudin’s selectivity index of two minerals increased from 1.75 to 3.78.
