Manganese is widely used in the iron and steel industry, batteries and other fields. The amount of the manganese oxide ores existing in China coeval with iron and their manganese-to-iron ratio is low. A study was conducted on a synchronous reduction roasting-magnetic separation of a ferromanganese ore with high content of iron taken from South Africa using CO …

There are four known modifications of manganese. Metal alloys can stabilize any of them and obtain solid solutions with very different properties. Manganese is a heavy metal with an atomic weight of more than 40. It is passivated in the air and covered with a dense oxide film that prevents further reaction with oxygen.
