Previous studies have proved that theplexes of benzohydroxamic acid PbBHA are effective collectors of scheelite flotations however, the separation of scheelite from calcite needs depressants with high selectivity. In this study, we reported a novel depressant for calcite minerals, and PbBHA served as the collector of scheelite.

01/05/2018· Oleic acid has been extensively used in the flotation of scheelite, and is still used today, notably in form of sodium oleate. Sodium oleate is the Na soap of the unsaturated oleic acids. As an anionic collector, its adsorption takes place on cationic sites Ca 2+ on the scheelite surface.
Slime coating3 is also another factor adversely affecting the flotation of scheelite. The present study is an attempt to improve the selectivity of separation of scheelite, based on the flotation of pure clacite scheelite system using sodium oleate as collector. EXPERIMENTAL : Materials 1, Calcite
The flotation separation of scheelite from calcite using sodium oleate as collector and acidified sodium silicate as depressant has been studied the results show that sodium oleate has collecting ability to both scheelite and calcite and the flotation.
