摘　　要：根据矿物性质差异,对某碳酸盐萤石矿进行了可选性研究。通过大量的试验找出了有效抑制方解石的抑制剂,并且选用一段磨矿—二粗—二扫—五精的脱泥、脱方解石和选萤石的工艺流程,成功地实现了萤石与方解石的分离,试验最终获得高品位萤石精矿,CaF2含量大于95%,碳酸钙含量3%,CaF2回收率76.61%。According to the difference of the mineral property, an investigation is made of the floatability and process flowsheet of a certain fluorite ore. A kind of depressant is found base on lots of works. A fluorite concentrate grading of 95 % CaF2 and assaying of 3 % CaCO3 and a recovery of 76.61% are obtained by processing using a single flotation flowsheet consisting of one stage grinding-two stage roughing-two stage scavenging and five stage cleaning.
