froth flotation of silicate minerals

International Journal of Coal Preparation and UtilizationRemovability of fluorine from coal by froth flotation Flotation is widely used to treat fine-coal particles and its principle depends on the differences in the surface property that can be changed via using different flotation agents such as collector frother and depressant -froth flotation of silicate minerals-,Use of depressants in the direct flotation of a silicate This work carried out with a silicate-carbonate phosphate ore aimed at studying the performance of depressant agents of different origins in the separation of apatite from the contaminants calcite and silicates by laboratory scale flotation …… Get More
