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. Repeatability and precision are absolute requirements of any modern production process. Early designs of production and fabrication machines had some form of a control system to automate the process and ensure repeatability and precision. While most of those systems were mechanically automated using cams, belts and gears, machining equipment that can manufacture custom parts like Routers, mills, and lathes had to be controlled and operated by a human operator which was not as accurate, efficient or repeatable.

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.
