Abstract：Mineral processing tests were carried out for a low-grade copper ore from South America containing 0.027% Mo and 0.45% Cu. After optimization of the reagent regime, a close-circuit test by adopting a flowsheet of Cu-Mo bulk flotation plus Cu/Mo separation resulted in a copper concentrate grading 26.93% Cu at 81.96% recovery, and a molybdenum concentrate grading 25.32% Mo at 76.24% recovery. Therewith, copper and molybdenum resources in the lean ore can be effectively recovered.
