| Abstract: |
| In view of the unsatisfactory production index of the re-election and flotation combined process of a high-calcium scheelite in Yunnan. This paper used the process of “Pre-desulfurization and decarburization, heating and one coarse and three fine three sweeps”. Finally, it obtained a tungsten coarse concentrate containing 58.7% WO3 and a recovery rate of 75.59%, which provided support for the technical transformation of the enterprise. |
