靖西县锰矿是广西生产电池锰粉的主要基地之一。文章通过选矿厂流程查定数据与产品分析,指出了目前生产技术经济指标不好的主要原因:入选粒度过粗。设备处理能力与人选矿量不平衡,流程结构不合理。笔者根据原矿性质及今后发展动向。进行了试验室研究,提出了新的选别流程,仅精矿总回收率就较原生产流程提高了17.39%,有效利用 MnO_2 资源。
Jingxi manganese ore production in Guangxi manganese is one of the main base of manganese. Through the ore dressing plant process identification data and product analysis, the paper points out the main reasons for the poor technical economic indicators of the current production technology: the selected grain size is too coarse. Equipment processing capacity and mineral resources are unbalanced, the process structure is irrational. The author based on the nature and future development of ore. Conducted a laboratory study, proposed a new sorting process, only the total recovery of the concentrate than the original production process increased by 17.39%, the effective use of MnO2 resources.
