一、前言萤石与碳酸盐矿物(方解石等)的分离被认为是萤石矿浮选的三大难题之一。在碳酸钠和水玻璃介质中以油酸作捕收剂,萤石和碳酸盐矿物的可浮性很相近,它们几乎同步进入泡沫。江西省德安萤石矿选厂沿用传统工艺,处理手选碎屑(CaF_2≥70%,CaCO_3≤0.5%)曾获较好指标,改由原矿(CaF_2=49%,CaCO_3>1.0%)浮选,最终精矿品位≤98% First, the foreword The separation of fluorite and carbonate minerals (calcite, etc.) is considered as one of the three major problems of flotation of fluorite ore. Flotation of fluorite and carbonate minerals is similar with oleic acid as a collector in sodium carbonate and water glass media, and they enter the foam almost simultaneously. The fluorite ore processing plant in De’an, Jiangxi province, has been given a good indicator of handling hand-made detritus (CaF_2 ≥70%, CaCO_3≤0.5%) by using the traditional process instead of floating (CaF_2 = 49%, CaCO_3> 1.0%) float Election, the final concentrate grade ≤ 98%
