In secondary manganese oxide ore deposits mainly weathering, as well as primary and secondary oxide ores some of the deposition and hydrothermal deposits. Manganese ore was mainly hard manganese ore, manganese ore and water, manganese ore; gangue minerals mainly silicates, but also carbonate minerals, frequently with iron, phosphorus, and nickel, cobalt and other ingredients.

The ore dressing method of manganese oxide ore is mainly based on re-election. Weathered manganese oxide ore often contains a large amount of slime and fine ore, and the production uses a washing-re-election method. The ore is washed and removed to remove the slime, and the obtained net ore can be used as a finished ore, and some need to be selected by jigging and shaking. Washing overflows sometimes require further recovery by re-election or strong magnetic separation. Some sedimentary primary manganese oxide ore, due to the depletion of mining, the use of heavy medium and jigging re-election to remove gangue, to obtain massive concentrate.
In iron-bearing manganese oxide ore, the iron mineral is mainly limonite. Iron and manganese are difficult to separate by re-election, flotation or strong magnetic separation, and a reduction roasting magnetic separation method is required. The industry has adopted a washing-reduction roasting magnetic separation-re-election process.
