| Abstract: | A mineral processing experiment was conducted with a copper-bearing polymetallic ore grading 1.00% Cu, 0.067% Mo and 3.04 g/t Au from Qinghai. A flowsheet consisting sequentially of Cu-Mo iso-flotation, Cu/Mo separation and S flotation from Cu/Mo bulk flotation tailings was adopted. The closed-circuit test produced a molybdenum concentrate grading 48.52% Mo at 86.49% recovery, a copper concentrate grading 19.44% Cu at 94.72% recovery with gold content of 57.10 g/t at 90.44% recovery, and a sulfur concentrate grading 36.56% S at 32.84% recovery. |
