| Abstract: | A Guangxi wolframite with WO3 grade of 0.41% is a type quartz vein of wolframite deposit. Using the process of pre-classification and small particles shaking table separation and large particles grinding and reverse flotation and magnetic to remove the gangue minerals such as sericite and quartz, the wolframite concentrate with yield of 0.47% and WO3 grade of 67.31% and the recovery rate of 77.16% can be obtained. Tungsten resources can be better recovered. |
