摘　　要：针对黑龙江某鳞片石墨矿特点,开发了新型高效浮选药剂并进行了浮选试验研究。结果表明,以新型药剂CYM-11为捕收剂、CYQ-01为起泡剂,经8次再磨、9次精选闭路浮选,可获得固定碳含量(质量分数)96.63%、回收率95.69%的石墨精矿产品,其中+0.15 mm粒级产率11.38%、固定碳含量(质量分数)96.04%,大鳞片石墨在选矿过程中得到较好保护。According to the mineral properties of a kind of flake graphite ore in Heilongjiang Province,a new efficient flotation reagent was developed and then adopted in a flotation experiment.Results show that with the new reagent of CYM-11 as a collector,CYQ-01 as a foaming agent,an experiment with a closed-circuit flowsheet consisting of eight-stage regrinding and nine-stage cleaning can yield an graphite concentrate with fixed carbon content of 96.63%at 95.69%recovery,among which the graphite concentrate at a size of+0.15 mm can be produced with a yield of 11.38%and fixed carbon content of 96.04%in mass fraction.It is shown that the large flake graphite can be well protected during the course of mineral processing.
