Pdf The Role Of Alkaline Earth Cations In Flotation

The flotation responses of quartz and feldspar with alkylsulfonates collectors in the presence of some alkaline earth metals were studied. The activation mechanism in these systems is discussed in terms of hemimicellization and surface

Impact Of Sodium Hexametaphosphate On The Flotation Of

Interestingly, the proportion of hydrophilic quartz minerals ending up in the concentrate is lower for HEDP, with only 1.9 quartz at a recovery of 21.5 compared to the 2.7 of quartz at a recovery of 24.9 when using SHMP. The paper contributes in general to understanding the complexity of the depressant responses in froth flotation.

Flotation Properties Of Silicon Carbide I Flotation Of

Jan 01, 1997 Concentration of amine necessary for obtaining complete flotation recovery of SiC is two orders lower than in the case of quartz. The mechanism of amine action in the flotation of SiC consist in the adsorption of amine as a result of its electrostatic interaction with the negatively charged SiC surface.
