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 fine-grained inlays. There are many types of manganese ore mining process methods and manganese ore beneficiation equipment.
