Manganese processing Britannica

Manganese processing, preparation of the ore for use in various products.. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal.

Wealth in the Oceans: Deep Sea Mining on the Horizon?

During mining, sediments on the sea floor are disturbed and the presence of particulate matter can alter food supply. Large amounts of disturbed sediment can also have a smothering effect on certain sea floor residents. Mining manganese nodules is expected to occur over large areas. In the process all living organisms on the sea
