| Abstract: |
| The molybdenum concentrate tailings in a mine in Luoyang contain 0.526 % copper, which mainly exists in the form of chalcopyrite and has comprehensive recycling value. The other minerals in the tailings are mainly quartz, chlorite and pyrite. The particle size of tailings is very fine, and the content of pyrite is high, so it is difficult to separate copper and sulfur. In view of these characteristics, on the basis of conditional tests, the reagent system was optimized, and the flotation process of " one roughing, three cleaning and three scavenging " was adopted. Finally, a copper concentrate with a copper grade of 24.18 % and a recovery rate of 85.65 % was obtained, and the effective recovery of valuable metal copper was realized. |
