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

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 ...

Although it occurs naturally in manganese ores, manganous dioxide, which finds its principal application as a depolarizer in drycell batteries, is usually produced synthetically. Manganese ore is reduced and then leached with sulfuric acid. The solution is purified, and manganous dioxide is obtained by electrolysis.

Highpurity Mn is necessary for high strength steel production. However, the availability of metal Mn is limited to a few countries. Therefore, as an alternative to direct purchasing of metal Mn, a process for Mn recovery was investigated. Waste dry cell batteries are considered to be one of the most feasible Mn sources. We have developed a high efficiency chemical separation system. This ...
