根据黄斜锰矿石泥化严重,并且在机选过程又易产生次生泥化的特性,研究了原矿轻搅拌—分级强磁选的简单工艺流程,所得精矿经烧结后可达二级冶金锰矿石标准,精矿中Ag(原矿80g/t)提高到160g/t。
According to the severe muddy degree of Huanghuang manganese ore and the characteristics of secondary muddy generation in the machine selection process, the simple technological process of light agitation-grading strong magnetic separation of raw ore is studied. The obtained concentrate can reach the second grade after sintering Manganese ore standard, concentrate in Ag (ore 80g / t) increased to 160g / t.
