PDF Manganese Industry Analysis Implications for Project Finance

It is commonly obtained through manganese ore in the form of manganese oxide (also known as pyrolusite), or through iron ores. Manganese production is thus often subsumed under iron mining. Besides their ores being regularly obtained from the same mines, manganese and iron are further linked due to their complementarity in steel production.

Physical properties Manganese is a silverygray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. [7] Manganese metal and its common ions are paramagnetic. [8] Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. [citation needed] Isotopes
