我国湖南省柿竹园矿床是特大型钨、钼、铋、萤石、锡多金属矿床。冶金部矿冶研究总院、冶金部矿冶研究所、柿竹园多金属矿等单位与湖南冶金研究所合作,对该矿区矿石选矿工艺进行了研究;并对其云英—矽卡岩型矿石进行了为时五年工业试验.试验流程是:粗磨—重选回收部分粗粒钨矿物;混合浮选黑白钨;重选和浮选粗精矿分别精选;混合—优先浮选流程回收钼铋矿物;浮选法回收萤石。上述流程获得较好的指标。WO_3、Mo、Bi、CaF_2回收率分别为81.69%、83.55%、68.29%、28.76%。白钨精矿、黑钨精矿、钼精矿、铋精矿和萤石精矿品位分别达到67.52%、66.29%、46.72%、29.17%、97.31%。 China’s Shushuanyuan deposit in Hunan Province is a large tungsten, molybdenum, bismuth, fluorite, tin polymetallic deposits. Ministry of Metallurgical Research Institute of Mining and Metallurgy, Ministry of Metallurgy Institute of Mining and Metallurgy, Shizhuyuan polymetallic mines and other units in cooperation with the Hunan Institute of Metallurgy, the ore beneficiation process were studied; and its Ying-skarn type Ore was carried out for a period of five years of industrial testing.The test procedure is: Rough grinding - re-election recovery of part of the coarse-grained tungsten minerals; mixed flotation of black and white tungsten; re-election and flotation of rough concentrate were selected; mixed-priority flotation process Recycling molybdenum bismuth minerals; flotation recovery fluorite. The above process to obtain better indicators. The recoveries of WO_3, Mo, Bi and CaF_2 were 81.69%, 83.55%, 68.29% and 28.76%, respectively. The contents of scheelite, wolframite, molybdenum concentrate, bismuth concentrate and fluorite concentrate reached 67.52%, 66.29%, 46.72%, 29.17% and 97.31%, respectively.
