湘潭锰矿贫锰矿石系微细粒嵌布的难选矿石,即使经过细磨也难以达到单体解离,因而采用机械选矿法处理效果较差。国内的试验研究结果表明,采用强磁选法能取得一定效果。可是近期强磁设备尚不能妥善解决。根据矿石的重液分析表明,粗粒级与细粒级的选别效果基本一致。同时由于含锰富的集合体与含锰贫的集合体及脉石之间比重差很小 Xiangtan manganese ore poor manganese ore micro-fine embedded embedded refractory ore, even after fine grinding is difficult to achieve monomer dissociation, so the mechanical processing method is less effective. The domestic experimental results show that the use of strong magnetic separation method can achieve some results. However, the recent strong magnetic equipment can not properly solve. According to the ore heavy liquid analysis shows that the classification of coarse and fine grade basically the same. At the same time, due to the manganese-rich aggregates and manganese-poor aggregates and gangue ratio difference between very small
