Manganese processing - Manganese processing - The metal and its alloys: More than 90 percent of the manganese produced goes into metallurgical applications, the pure metal being used in copper and aluminum alloys and ferromanganese and silicomanganese employed in steel and cast iron. Most manganese is consumed as high-carbon ferromanganese for addition to carbon steels.
