Fluorite Depressant - Froth Flotation Sulphide and Oxide ...

Fluorite flotation: please anybody suggest good depressants for silica and calcite in fluorite flotation. My specs are now: fluorspar has CaF2 =60%, CaCO3=19.5% and SiO2=9.7%, I am already using water glass, pH=10, with oleac acid as collecter. Concentrate has CaF2=88.7%, eliminated silica to 0.43% but still there is CaCO3 about 5%.

Flotation Depressants - Mineral Processing and Metallurgy

First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color. This is because the froth is becoming purer as ...
