摘　　要：为提高钨回收率,某多金属选厂对钨选矿系统工艺流程与设备进行了全面的改进。在黑白钨混浮粗选段的第一次粗选后,运用高梯度磁选机提前分选出黑钨,钨粗选段的回收率提高了1.75%;在精选段,黑钨与白钨分路精选,代替原来先选白钨后选黑钨工艺,精选段的回收率提高了1.09%。在尾矿再回收段,黑钨精选的尾矿返回到钨粗选段构成闭路;白钨精选的尾矿用悬振锥面选矿机回收黑钨,收尾段回收率达到32.73%。综合各段回收率的提高,钨的总回收率提高了3.61%,并获得了预期的经济效益。A multi-metallic separation plant improved its tungsten processing the recovery rate. High gradient magnetic separator was applied to the se flow sheet and facilities to optimize parated wolframite after first time separation. The recovery rate in the tungsten coarse separation stage increased by 1.75 %. Shunt selection of wolframite and scheelite replaced the former processing technology in the fine processing stage, whose recovery rate increased by 1.09 %. In the tailings recycling stage, the tailings processing, which composes closed circuit process. Suspension tailings of scheelite. The recovery rate reaches 32.73 %. The total of wolframite fine processing returns to the coarse vibration cone separator is applied to recycle the recoverv rate increased bv 3.61%.
