NOVELTY - Use of high-efficiency copper collector M1 comprises (i) searching copper collector to replace medicine through continuous filtering, and applying excellent copper-molybdenum flotation collecting agent to optimize mixed flotation index in porphyry copper and molybdenum ore flotation process; (ii) mature small ore dressing test mature, developing small industrial test, searching medicine deficiency, optimizing proportion, and in the industrial test is stable under the condition of selecting ore flotation or separation operation of the flow inspection, and submitting feasibility report; (iii) using the sample for assay analysis, and performing the number mass flow calculation, by calculating, evaluating the mixed flotation process rough scavenging, selecting efficiency of selecting operation, and selecting efficiency comprises yield, concentrate grade and recovery rate, and carrying out load check calculation to each operation. USE - Method for research and application of new efficient copper collector M1. ADVANTAGE - The method improves copper recycling rate by 0.34 % points, and improves molybdenum recycling rate of 1.48 percentage points.
