On the Mineral Processing Technology of a Scheelite

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 %.
