Experimental Study on Improving Quality and Reducing Impurities of Metallurgical Grade Fluorite Concentrate
An experimental study on a metallurgical grade fluorite concentrate with CaF2 content of 70.34%was conducted to upgrade fluorite concentrate quality by reducing impurities therein.The results of the full process test show that by adopting a process of high intensity magnetic separation for reducing silicon,followed by flotation of non-magnetic minerals for reducing calcium,the experiment produces a fluorite concentrate grading of 91.95%CaF2 at 76.52%recovery,with a yield of 58.30%.It is shown that the concentrate meets the raw material standards for anhydrous hydrofluoric acid production.
