选矿一公司的主要产品为钼精矿,其设计原矿处理能力为3 000 t/d。原工艺流程为一段球磨分级后进入粗选段,粗选段流程为一次粗选、一次精选及两次扫选。为满足逐步提高的生产要求,选矿一公司进行了粗选再磨流程改造,在粗选段进行二次磨矿旋流分级及粗选浮选柱改造,将原矿处理量由4 300t/d提高到5 200 t/d,提高了精矿产量和回收率。
The main product of a beneficiation company is molybdenum concentrates with a designed raw ore handling capacity of 3 000 t / d. The original process for a ball milling grading into the rougher section, rougher section of the process is a rougher, a selection and two sweeps. In order to meet the gradually increasing production requirements, a beneficiation company conducted a revamping of the roughing and re-grinding process, a secondary grinding cyclone classification and a rougher flotation column reformation in the rougher section, increasing the ore handling capacity from 4 300 t / d to 5 200 t / d, improve the concentrate production and recovery rate.
