2022-1-12 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.

The present invention provides methods for making manganese sulfide without the need for recycling a significant amount of manganese sulfide back to the reaction chamber. The methods are performed by admixing substantially pure manganese, substantially pure sulfur, and iron pyrite. The manganese and sulfur are then reacted to form manganese sulfide.
