大厂 10 0号矿石中磁黄铁矿含量高 ,严重地影响选厂生产指标 .采用 ZCT中磁筒式高效磁选机为磁选设备的粗粒磁选工艺 ,不仅磁黄铁矿的脱除率高 ,达到 77.11% ,而且锡、铅、锌在磁性矿物中的损失少 ,仅分别为 1.76% ,3.0 7% ,1.56% .由于脱除磁黄铁矿后 ,排除了它对后续浮选和重选作业的影响 ,因此锡、铅、锌指标明显提高 ,回收率分别提高了 6.38% ,1.32 % ,4 .79% .同时 ,明显地减少了浮选药剂的用量 ,减少了对环境的污染 ,取得良好的经济效益和社会效益 .
Dachang 10 0 ore pyrrhotite high, seriously affecting the selection of plant production indicators.ZCT medium magnetic separator magnetic separator for the magnetic separation equipment coarse magnetic separation process, not only the pyrite off The removal rate is 77.11%, and the loss of tin, lead and zinc in magnetic minerals is less, only 1.76%, 3.07% and 1.56%, respectively. Due to the removal of pyrrhotite, The indexes of tin, lead and zinc increased obviously, the recovery rates increased by 6.38%, 1.32% and 4.79%, respectively. Meanwhile, the dosage of flotation reagents was obviously reduced, Of the pollution, and achieved good economic and social benefits.
