某白钨矿选矿工艺试验研究

摘要

Small-scaled laboratory tests were performed on a scheelite of Xinjiang in light of its characteristics. The technical flow and conditions for separating the scheelite were studied. Experimental results show that the scheelite is treated through gravity concentration under the selected technical condition, obtaining a tungsten concentrate containing 67.34 % WO3 with recovery of 61.53 %. When treated by a combination process of flotation-gravity concentration, a tungsten concentrate containing 75.50 % WO3 is obtained with recovery rate of 67.29 %.%针对新疆某白钨矿矿石性质,进行了实验室小型工艺试验研究.试验结果表明,重选法可获得钨精矿含WO367.34％、回收率为61.53％,浮选-重选联合工艺流程可获得钨精矿含WO375.50％,回收率为67.29％.
