| Abstract: |
| According to a refractory Copper-Cobalt ore in R.D.Congo with fine particle size distribution, high content of secondary copper sulphides and existence of easy-floating silica minerals, process of “fine grinding, pre-floation of easy-floating gangues, partial selective-buld flotation” is developed to recover valuable minerals. By this technology, from the raw ore with Cu grade of 2.98% and Co grade of 0.030%, the final concentrate grading 28.54% Cu and 0.14% Co were obtained, and recovery of Cu and Co are 93.41% and 44.47% respectively. |
