跳汰选矿重选回路提升金矿回收率

责任编辑:金工机械 发表时间:2016-06-19 16:04

  某矿床具有资源储量为5800万t矿石,金品位为2.65g/t。对给矿磨至140μm占80%的氰化浸出渣进行传统的重液分离,结果表明,新 的矿床中与细粒硫化矿物连生的含金黄铁矿的量比老矿床的量大。为了使金得到最优的回收,用重选回路提高精矿品位是必要的,确定选矿厂建设所需要的参数的计 划已经开始。本文对选用跳汰机为主的重选回路的选矿工作进行描述。

  磨矿工段的处理能力为360~600t/h。尽管每台跳汰机的标称处理能力为85t/h,对于某些混合矿,处理能力也可以增加到100t/h。 试验期问设备处理能力曾达到120t/h,但没有足够的时间确定在此条件下设备能取得怎样的基本选矿指标。可以认为,这不是临界状态,因为氧化矿含量高的 矿石的处理量最高,而氧化矿的总回收率与跳汰回路关系比较小。
