Application Research on a New Type of Molybdenum Collector MK-01 in Separation of Molybdenum of Mackeng Iron Tailings
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.
