An experimental study with a novel flotation reagent was carried out for some refractory low-grade polymetallic ore from Henan Province, and a process of Cu-Mo bulk flotation, followed by Cu/Mo separation was adopted in the experiment. With a processing flow consisting of a Cu-Mo bulk flotation (including two stages of roughing, one stage of cleaning, and two stages of scavenging) with L43 as a collector and L56 as a frother, followed by regrinding of the obtained Cu-Mo bulk concentrate, and Cu/Mo separation (including one stage of roughing, three stages of cleaning and three stages of scavenging) with L789 as a depressant, the experiment produced a molybdenum concentrate grading 50.780% Mo, 0.602% Cu with 65.30% Mo recovery and 4.72% Cu recovery, and a copper concentrate grading 0.165% Cu and 0.362% Mo with recoveries of 4.49% Cu and 1.61% Mo. It is shown 90.79% Cu is recovered into the mixed tailings.
