Test for a Low-grade Scheelite Ore with Improving the Grade of Concentrate by Optimization of Agents
There are 0.27% WO3 in a scheelite Ore. The grade of scheelite concentrate produced on site is 53.11%. Because the grade of the concentrate is low, the pricing coefficient of the concentrate is low. In order to improve the grade of scheelite concentrate, according to the properties of the ore, combi...

| description | There are 0.27% WO3 in a scheelite Ore. The grade of scheelite concentrate produced on site is 53.11%. Because the grade of the concentrate is low, the pricing coefficient of the concentrate is low. In order to improve the grade of scheelite concentrate, according to the properties of the ore, combined collector was used for flotation at room temperature, sodium sulfide was used as an auxiliary inhibitor at heating flotation. After the flotation reagent is optimized, the grade of scheelite concentrate can be significantly increased to 66.18%, the recovery rate of the concentrate remains basically unchanged，and the dosage of inhibitor sodium silicate is significantly reduced. The technical and economic effects of the optimized process are significantly improved. |
