摘　　要：河南某萤石矿含33.8%CaF_(2),4%CaCO_(3),44.52%SiO_(3),属于高硅石英型萤石矿。在矿物工艺学的基础上,针对本矿区矿石特性,进行了一系列的选矿试验研究工作。在磨矿细度-0.074 mm占70%、矿浆pH为中性的条件下,油酸钠作捕收剂,选用混合抑制剂S-824,最终可得到萤石精矿CaF_(2)品位为97.57%,回收率90.23%,实现了萤石与石英的高效分离。A fluorite ore in Henan Province contains 33.8% CaF_(2), 4% CaCO_(3), and 44.52% SiO_(3), belonging to a high-silica quartz fluorite ore. On the basis of mineral technology, a series of mineral processing experiments were carried out according to the ore characteristics in the mining area. Under the conditions of 70% grinding fineness of-0.074 mm and neutral pH of ore slurry, sodium oleate was used as collector and mixed inhibitor S-824 was selected. Finally, the CaF_(2) grade of fluorite concentrate was 97.57%, and the recovery rate was 90.23%, realizing the efficient separation of fluorite and quartz.
