Manganese-rich ore resources are mainly concentrated in South Africa, Gabon, Brazil and Australia. For example, the Kalahari mine in South Africa has a manganese ore grade of 30-50 percent, the Groote Eylandt mine in Australia has a manganese ore grade of 40-50 percent, and India, Kazakhstan and Mexico are medium-grade manganese resource countries.

Manganese - Wikipedia

Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese metal and its common ions are paramagnetic. Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen.
