2021-4-27  Abstract: Froth flotation is the most effective industrial method used for the separation of fine-grained minerals. The main problem for the flotation of complex ores, obviously, is the negative effect of the interactions among minerals in slurry, which leads tothe variation of surface properties in the process of separation. In this review,
