Abstract: |
In For flotation column on the microgranular mineral flotation and increase the concentrate grade, the advantages of simple combination of dahongshan copper mine copper flotation process flexibility, mill plant in dahongshan copper mine two part adopts diverted from the production process pulp CPT flotation column experiment, combining cleaner tailings MLA test research of coarse flotation concentrate and then grinding and grinding in both cases the technical and economic indicators, don"t get rough concentrate grinding process of flotation column and flotation machine, compared to concentrate grade is increased by 1.00%; The operating recovery rate increased by 0.45 percentage points. Compared with the flotation machine, the grade of the flotation column in the regrinding process of coarse concentrate has been improved by 3.62 percent. The operating recovery rate increased by 0.74 percentage points. |
