Beneficiation of low grade manganese ore fines

In smelting the recovery of iron in alloy is about 90 per cent while that of manganese is only about 68 to 80 per cent. The Mn:Fe ratio generally specified in the ore is 7:1 for high- carbon ferro-manganese containing 75 per cent manganese.

Manganese Ore Processing - 911 Metallurgist

27/04/2016  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.
