EPA1Methods of making manganese sulfide

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.
