Manganese is a critical mineral in America and the development of new methods of beneficiation is highly desirable for our national defenses. While much investigational work has been carried out by the U.S. Bureau of Mines and others, there is still a need for more efficient reagents to make many ores economically amenable to the flotation process.

Manganese (Mn) is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to
