舞阳选厂二系列工艺流程是按处理原生矿设计的,因暂无原生矿采出,只能处理混合矿,其结果是指标低,资源浪费严重。因此,要对二系列进行改造。改造分三步进行:第一步把原流程改造成两段磨矿一段磁选的流程,这样不仅生产出的精矿质量符合公司要求,而且回收率可提高5.02％;第二步把二系列的部分尾矿分流给一系列进行弱磁——强磁选,做到尽量多回收尾矿中的铁矿物;第三步把二系列改造成磁——重联合流程。通过以上三步改造,使二系列流程更加完善,不但可处理原生矿,而且也能处理混合矿,使采选生产灵活方便,并获得较高的技术经济指标。
Wuyang election process two series of plants is designed to deal with the primary ore, because no primary ore mining, can only deal with mixed mines, the result is a low indicator of serious waste of resources. Therefore, to reform the two series. The transformation is divided into three steps: the first step is to transform the original process into two sections of a magnetic separation process, so that not only the quality of the concentrate produced meets the requirements of the company but also the recovery rate can be increased by 5.02%. The second step is to replace the two series Part of the tailings diversion to a series of weak magnetic - strong magnetic separation, so as to recover as much iron ore tailings; The third step is to transform the two series of magnetic - heavy combined process. Through the above three steps of transformation, the two series of processes will be further improved. Not only the primary ore but also the mixed ore will be processed, which will make the mining and dressing production flexible and convenient and achieve higher technical and economic indicators.
