Role of sodium hexametaphosphate in flotation of a nickel ore 171 of the interacting particles as reflected by zeta potential measurements (Uddin et al., 2012; Trahar, 1981). Oppositely charged or near-neutral charged ultrafine particles tend to aggregate. Slime coating can be controlled using dispersants, which adsorb preferentially onto slimes, reversing and/or increasing the surface charge ...

The Influencing Mechanisms of Sodium

In a Cu–Au ore flotation with chalcopyrite as the major valuable Cu mineral in the presence of bentonite, Wang et al. found that divalent cations of Mg 2+ and Ca 2+ had a more significant role than monovalent cations of Na + and K + in reducing bentonite viscosity due to stronger compression of electrical double layers of bentonite particles, thereby increasing flotation efficiency, similar ...
