重选

目前重选只用于选别结构简单、嵌布粒度较粗的锰矿石，特别适用于密度较大的氧化锰矿石。常用方法有重介质选矿、跳汰选矿和摇床选矿。

目前我国处理氧化锰矿的工艺流程，一般是将矿石破碎至６～０mm或１０～０mm，然后进行分组，粗级别的进行跳汰，细级别的送摇床选。设备多为哈兹式往复型跳汰机和６-ｓ型摇床。

Re-election

Currently re-election only for sorting simple structure, disseminated coarse granularity manganese ore, especially suitable for high density of oxide ore. Common methods of heavy media beneficiation jig beneficiation and dressing shaker.

At present, China manganese oxide treatment process, the general is broken ore to 6 ~ 0mm or 10 ~ 0mm, then grouped to send shaker election jigging coarse level and fine level. Equipment and more Haz reciprocating type jig and 6-s-type shaker.
