These results summarized in the data sheets of the Appendix show that flotation of these ores to a 97 percent fluorite concentrate is possible through the use of a split product flowsheet. Fluorite still unliberated after a 200 mesh grind and sericitic slimes may be removed
Chat OnlineThe effect of particle size distribution on froth stability in flotation. Froth flotation is a complex and widely used separation technique which relies on differences in the surface properties of the desired particles to the unwanted particles. 110 mm in diameter and 1.3 mm in thickness centred below the impeller.
