Systematic process mineralogy studies were conducted on a refractory copper-molybdenum polysulfide ore in Yunnan, and a new collector KMC531 was developed according to its properties. The effect of KMC531 on its collection performance in copper and molybdenum was clarified. The results show that under optimized conditions, a closed-circuit flotation test on the raw ore assaying 0.28% Cu and 0.011% Mo yielded a copper-molybdenum bulk concentrate grading 23.51% Cu and 0.92% Mo with recoveries of 82.86% Cu and 86.17% Mo, indicating efficient enrichment of copper and molybdenum.
