Fluorite ore dressing technology

Fluorite is an important industrial raw material with a wide range of uses. A Inner Mongolia fluorite containing 63.93% of CaF2, fluorite disseminated grain size finer, the gangue minerals are mainly quartz, mica and calcite, quartz belonging - fluorite - calcitic hard dressing stone. Through the mineral processing test of a fluorite mine in Inner Mongolia, a reasonable pharmaceutical system and process flow were determined, in which a modified fatty acid salt collector YSB-2 was used, which was used at a normal temperature of 24 ° C. Fine, medium-concentration returns to the fine I" process, obtaining a high-grade fluorite concentrate with a grade of 98.70%, a recovery of 89.20%, a SiO2 content of 0.93%, and a CaCO3 content of less than 0.37%.

1. The fluorite ore has a CaF2 content of 63.93%, the main harmful elements are Si, Al, Fe and Ca in carbonate; the useful minerals are mainly fluorite, and the gangue minerals are mainly quartz, calcite, mica (biotite and muscovite), small amounts of pyrite, limonite and so on.

2. YSB-2 and oleic acid beneficiation efficiency are the same, but YSB-2 has good solubility and good low temperature resistance. Above 10 °C, temperature has little effect on the effect of YSB-2 and minerals, and the effect on concentrate index is not significant. .

3. The test results show that when the grinding fineness is -0.074mm, the content is 98%, the "one crude seven fine", alkaline (pH = 9.0) rough selection, weak acid (pH = 6.0) selection, medium The concentrate is returned to the refined I process, and a high-grade fluorite concentrate with a yield of 57.77%, a grade of 98.70%, a recovery of 89.20%, a SiO2 content of 0.93%, and a CaCO3 content of less than 0.37% can be obtained.
