Elemental manganese readily combines with oxygen, carbon, and silicon to form a long list of manganese minerals. Manganese ores generally contain 25 to 45 percent manganese, mostly in oxide (or hydroxide) and carbonate minerals. Manganese ores are widespread, but most of the world''s supply is from a small number of manganese mining districts.
Manganese ore can also be sorted by the flotation method. The manganese ore flotation machine is mainly used for the flotation of manganese carbonate ore and polymetallic manganese ore, and is suitable for ore sorting of finegrained inlays. There are many types of manganese ore mining process methods and manganese ore beneficiation equipment.
