摘要： 通过对内蒙古某细粒嵌布萤石矿的浮选试验研究，确定了合理的药剂制度和工艺流程。以自行研制的改性脂肪酸盐YSB-2为捕收剂，在常温（24 ℃）下，采用弱碱性（pH=9.0）1次粗选，弱酸性（pH=6.0）7次精选，精Ⅰ尾矿作为最终尾矿丢弃，其余中矿集中返回到精Ⅰ的碱酸工艺流程，获得了品位为98.70%、回收率为89.20%、SiO₂含量为0.93%、CaCO₃含量小于0.37%的高品级萤石精矿。

Abstract: A rational reagent regime and process for a finely disseminated fluorite ore from Inner Mongolia were determined through flotation test research.The flotation test adpoted the self-developed modified fatty acid salt YSB-2 as collector and was carried out at a normal temperature (24 ℃).The process was composed of one rougher in weakly alkaline medium（pH=9.0）and seven cleaners in weakly acidic medium (pH=6.0).The tail of cleaner I was the final tail and the middlings were concentrated and returned to the acidic-alkaline process.A high grade fluorite concentrate assaying CaF₂ 98.70% at a CaF₂ recovery of 89.20%, SiO₂ 0.93% and CaCO₃ below 0.37% was produced.

Key words: Finely disseminated fluorite, Acidic-alkaline flotation process, Collector YSB-2
