| Abstract: | For a low-grade associated scheelite and fluorite ore with WO3grade of 0.10%and CaF2 grade of 25.45%in Fujian province,the high-efficiency beneficiation reagent BK418independently developed by BGRIMM Technology Group was used as scheelite collector and BK410as fluorite collector.The ore was treated by the technological process of scheelite flotation at normal temperature-flotation of tungsten concentrate at normal temperature-flotation of fluorite from tailings of scheelite flotation at normal temperature.The grade of tungsten concentrate was 60.48%and the recovery of WO3 was 65.29%,and the grade of CaF2in fluorite concentrate is 90.64%and the recovery of CaF2is 55.34%.It provides a technical basis for the development and utilization of this type of low-grade associated scheelite and fluorite ore. |
