Experimental Study on the Beneficiation of Wolframite and Scheelite of Xinjiang

Based on the property of wolframite scheelite ore of Xinjiang,the process ofgravity concentration-flotation-gravity concentration and GYB +ZL combination collector was adopted,mixed concentrates of wolframite scheelite were obtained,the concentrates grading 65.23% WO3,at the recovery of 40.17%;flotation scheelite concentrate grade is 65.11%,at recovery of 28.64%;wolframite concentrate one grade is 50.02%,at recovery of 15.40%;wolframite concentrate two grade is 32.10%,at recovery of 7.06%;the total WO3 recovery is 91.27%.
