Difference Of Metallurgical And Chemical Grade Fluorite Ore Beneficiation
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.
