Depressing effect of sodium hexametaphosphate on apatite in flotation
Froth flotation is a typical method for separating phosphate minerals from other minerals (calcite, dolomite, quartz and rutile, etc.) [1,13–15]. Flotation is a physico-chemical separation process that utilizes the difference in surface properties of the valuable minerals and the unwanted gangue minerals [16–18].
Role of nanobubbles in the flotation of fine rutile particles
1. Introduction. The world's rutile resources mainly consist of primary rutile ores and coastal placers. Most primary rutile ores feature poor endowment, low grade, fine grain size, and a complex mineral composition (Chen et al., 2021).To effectively recover rutile, the rutile particles must be sufficiently ground to dissociate the monomers (Xu et …
