Fluorite ore flotation is a method of extracting fine-grained disseminated fluorite ore by means of flotation beneficiation. This method is mainly used to produce high-quality chemical grade fluorspar concentrate. Due to the higher requirements on the concentrate grade, it is also the only way to produce chemical-grade fluorspar powder ore.

The world reserves of tungsten are estimately 4.000.000 t W of which China holds about 40% (Bernhart, 2015).The five major types of tungsten ore deposits from which most ore is currently produced are skarn, vein/stockwork, porphyry, disseminated or greisen, and stratabound (BGS, 2011).Typical grades (WO 3 %), tungsten minerals, …
