Abstract
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. Iron pyrite regulates the reaction and enables the use of conventional equipment in the methods of the present invention. After the reaction ends, the manganese sulfide product is separated from the unreacted manganese, sulfur, and iron.
