The following sections provide a detailed explanation of the mechanism behind the ...

Calcite-Apatite Flotation

Calcite Flotation The effects of apatite and calcite supernatants on calcite flotation is to depress the flotation markedly in the neutral to alkaline pH (pH < 13) range. A comparison of the effects of added inorganics with those of the supernatants suggests that the depressing effect of apatite supernatant is the combined ...

Vanadium recovery from stone coal through roasting and flotation

The micro-flotation results showed that the Ca 2+ exhibited little impact on muscovite and calcite floatability with sodium oleate as collector, while the Al 3+ and Fe 3+ remarkably reduced the floatability differences between muscovite and calcite. In the presence of Al 3+ and Fe 3+, the muscovite was activated, and the calcite was depressed ...
