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

Tesla battery is also moving to highpurity manganese as its primary raw material so that batteries produced in its new factories contain onethird manganese, twothirds nickel, and zero cobalt (Nicholls 2021 ). Manganese prices are likely to increase over the next few years due to the widening gap between supply and demand (Barrera 2022 ).

The ferromanganese (FeMn) alloy is produced through the smeltingreduction of manganese ores in submerged arc furnaces. This process generates large amounts of furnace dust that is environmentally problematic for storage. Due to its fineness and high volatile content, this furnace dust cannot be recirculated through the process, either. Conventional MnO2 production requires the prereduction ...
