对某钼铜铁多金属矿矿石进行了工艺矿物学研究,该矿石是以钼为主、并生铜铁的多金属矿。根据矿石的性质,采用钼铜混合浮选混合精矿再分离—尾矿磁选选铁的工艺流程。铜钼混合浮选时,采用煤油、柴油混合捕收剂,有利于提高钼回收率,采用选铜特效捕收剂BK802,有利于提高铜的回收率。铜钼混合精矿分离时,采用煤油作为捕收剂,最终选择BK310进行铜钼分离。对铜钼混选尾矿进行了选铁实验,最适宜的磁场强度为0.12～0.16T之间。研究结果表明:在原矿铜品位0.082%的情况下,可以得到含铜品位15.16%、铜回收率80.54%的铜精矿;采用新型抑制剂BK310,一次分离三次精选即得到钼精矿钼品位50.87%,回收率85.94%;磁铁矿单体解离较好,一次粗选后再磨,得到铁精矿铁品位69.47%、铁回收率41.89%的铁精矿。
A molybdenum copper-iron polymetallic ore ore carried out a process of mineralogy, the ore is molybdenum-based, and the copper-iron polymetallic ore. According to the nature of the ore, the mixture of molybdenum and copper mixed flotation concentrates re-separation - tailings magnetic separation process of iron. Copper and molybdenum mixed flotation, the use of kerosene and diesel mixture collector, is conducive to increasing the recovery of molybdenum, copper selective effect collector BK802, help to improve the copper recovery. Copper and molybdenum mixed concentrate separation, the use of kerosene as a collector, the final choice BK310 copper and molybdenum separation. The copper-molybdenum mixed tailing was selected iron experiment, the most suitable magnetic field strength between 0.12 ~ 0.16T. The results show that copper concentrate with grade of 15.16% copper and copper recovery of 80.54% can be obtained under the condition of 0.082% grade of copper in ore; the molybdenum concentrate Molybdenum grade can be obtained by using one new inhibitor, BK310, 50.87%, the recovery rate of 85.94%; magnetite monomer dissociation is better, after a rough selection and then grinding, get iron concentrate iron grade 69.47%, iron recovery rate of 41.89% iron concentrate.
