为了考察回水对配矿后的辉钼矿浮选指标的影响,分别用生产回水和清水进行相同条件下的浮选试验。试验结果表明,相比清水,利用生产回水进行浮选可减小最佳磨矿细度以及捕收剂煤油和起泡剂2#油的用量,但会严重影响浮选指标,使精矿品位降低7.35%,回收率降低4%,选用回水浮选最终获得了品位为3.94%,回收率为89.40%的精矿产品。 In order to investigate the effect of backwater on the flotation index of molybdenite ore with ore, the flotation tests under the same conditions were respectively carried out with the production of backwater and clear water. The experimental results show that compared with clear water, the use of production backwater flotation can reduce the optimal grinding fineness and the amount of collector kerosene and foaming agent 2 # oil, but will seriously affect the flotation index so that the concentrate The grade is reduced by 7.35% and the recovery rate is reduced by 4%. The final products with the grade of 3.94% and the recovery rate of 89.40% are selected by the backwater flotation.
