Manganese is the main recovery metal in iron manganese ore, and the total content of manganese and iron is more than 30%. Compared with manganese oxide ore, iron manganese ore is more difficult to separate, and the difficulty lies in the separation of iron and manganese minerals.

Magnetic separation is usually the first option for iron beneficiation [57, 58], whereas acid leaching is used for extracting copper ore [59], during which heavy metals can be inadvertently...

The technological process of dealing with manganese oxide ore is generally crushing the ore to 6 ~ 0 mm or 10 ~ 0 mm, then classification, jigging at the coarse level and shaking at the fine level. The gravity separation equipment is mostly Haz reciprocating mineral jig and 6-S type shaking table. 3.

Manganese (Mn) extraction from iron-rich pyrolusite ore with cheap sulphur dioxide is considered to be the most promising method with advantages of rapid leaching rate and high leaching efficiency.
