In order to explore the effect of a new molybdenum collector MK-01 on the recovery index
of molybdenum from iron tailings in Makeng Mining，the laboratory test and industrial test of conventional
collector kerosene and new molybdenum collector MK-01 were carried out respectively. The results show
that when the first-stage grinding particle size is -0.074 mm accounting for 65.38%，and the regrinding par⁃
ticle size is -0.037 mm accounting for 83%，sodium silicate is used as the regulator，sodium sulfite+ zinc
sulfate is used as the inhibitor，and 2# oil is used as the foaming agent，the molybdenum concentrate with
molybdenum grade of 44.938% and recovery rate of 66.54% can be obtained in the laboratory closed-circuit
test by using MK-01 as the collector，compared with kerosene as the collector，the molybdenum grade and
recovery rate are increased by 0.636 and 2.96 percentage points，respectively. Molybdenum concentrate
with molybdenum grade of 42.26% and recovery of 62.71% can be obtained by industrial test. Compared
with kerosene as collector，the grade of molybdenum is similar，the recovery rate is increased by 0.72 per⁃
centage point，and the dosage of collector is reduced from 52 g/t to 42 g/t. It shows that the new molybdenum
ore collector MK-01 can replace the traditional molybdenum ore collector in Makeng Mining.
