重選

目前重選只用于選別結(jié)構(gòu)簡(jiǎn)單、嵌布粒度較粗的錳礦石，特別適用于密度較大的氧化錳礦石。常用方法有重介質(zhì)選礦、跳汰選礦和搖床選礦。

目前我國(guó)處理氧化錳礦的工藝流程，一般是將礦石破碎至６～０mm或１０～０mm，然后進(jìn)行分組，粗級(jí)別的進(jìn)行跳汰，細(xì)級(jí)別的送搖床選。設(shè)備多為哈茲式往復(fù)型跳汰機(jī)和６-ｓ型搖床。

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.
