我矿是国内投产最早,产量最大的酸级萤石的生产和出口基地,每年生产萤石精矿7～8万吨。其精矿的主成份和含杂均达到用户的要求,但产品粒度较粗-100目小于80％。针对此,我们将浮选最终精矿的泡沫产品,扬至高位稳压箱后,送入φ150mm旋流细筛,进口静压P≥0.4kg/cm~2,分级脱水后其沉砂浓度大于 Mine is the earliest and largest output of acid-grade fluorite production and export base in China, producing 70,000 to 80,000 tons of fluorite concentrate every year. The concentrate of the main ingredients and impurities meet the requirements of users, but the product size of coarse -100 less than 80%. In response to this, we will flotation of the final concentrate foam products, Yang to the high regulator box, sent φ150mm swirling fine sieve, imported static pressure P ≥ 0.4kg / cm ~ 2, grading dewatering grit concentration greater than
