  • Understanding the depression mechanism of sodium citrate ...

    2020-03-05  Due to these minerals similar soluble properties and structures, direct flotation is inefficient. Therefore, reverse flotation of carbonate gangue and depression of apatite has been practiced by predecessors [ 4, 6 ]. Thus, the understanding of depression mechanism of apatite and other calcicolous minerals flotation has attracted much attention.
