为保证精矿产量任务如数完成,一方面需继续提高选矿回收率,另一方面更重要的是提高选矿厂生产率,扩大低品位原矿的处理量。但选矿厂设计的生产能力有限,投入生产后经过一系列改进,虽然突破了设计指标,但较之完成精矿年产量计划所要求的生产率仍然为低。为解决这一关键问题,我厂在今年第一季 In order to ensure the completion of the tasks of concentrates production, we must continue to increase the recovery rate of beneficiation while, on the other hand, it is more important to increase the concentrator productivity and expand the throughput of low grade ore. However, the design capacity of the concentrator is limited. After a series of improvements have been put into production, the design indexes have been exceeded, but the productivity required for the completion of the annual production plan of concentrates remains low. To solve this key issue, I plant in the first quarter of this year
