摘要
选矿厂的铜钼选矿系统出现了透辉石类含铜钼矿石 ,使钼浮选钼精矿品位不稳定、回收率低。通过试验研究 ,提出了“低浓度 ( 18%～ 2 0 % ) ,低 pH值 (pH =8.5～ 9.5) ,高水玻璃( 4～ 6kg/t)”工艺 ,对生产流程和操作条件进行改造和完善 ,使钼精矿品位稳定在 4 5%以上 ,铜、钼回收率分别提高了 1.15%和 18.93%。
With the grade of molybdenum concentrate unsteady, the recovery is low in processing production of the concentrator. The author finds the best technological conditions of 'low density (18%～20%), low pH value(8.5～9.5) and high rate of Na 2SiO 3 (4～6kg/t)' through test research. After improvement of flowsheet and operation conditions, the molybdenum concentrate grade can be reached more than 45% controllably, and the recovery of copper and molybdenum can be increase 1.15% and 18.93% respectively.
