Beneficiation Experiment of a Carbonate Fluorite Ore in Guizhou
This is an essay in the field of mineral processing engineering.There is a 40.56%CaF2 in a Carbonate fluorite ore in Guizhou.The ore composition is complex and the content of carbonate gangue minerals is high.The flotation experiment was carried out with a new collector LY-14 developed by ourselves.Using the closed-circuit test process of"one coarse,six fine and one sweep",under the conditions of grinding fineness of-0.074 mm,content of 81.42%,dosage of Na2CO3 of 1 200 g/t,dosage of acidified sodium silicate of 1 200 g/t,dosage of tannin of 100 g/t and dosage of collector LY-14 of 600 g/t,fluorite concentrate with CaF2 grade of 96.35%and CaF2 recovery of 91.47%was obtained.
