| Abstract: |
| The grade of CaF2 in a polymetallic ore tailing in YunNan is 6.51%. After hydrocyclone desliming, iron removal by magnetic separation, sulphide mineral removal by flotation, six times cleaning using acidic sodium silicate and sodium hexametaphosphate, impurity removal by high-intensity magnetic separation, the fluorite concentrate containing CaF2 95.68% can be obtained. |
