And the grade of concentrates does not change much from the one of the feed, which is 50%. It indicates that oleic acid cannot effectively separate scheelite from calcite when these two minerals coexist. This is consistent with the fact that some depressants are required when oleic acid is used as collector in the flotation practice of scheelite.Hu Y, et al. Cationic flotation of scheelite from calcite using quaternary ammonium salts as collector: ... Cationic flotation is a promising method for separating because ...
