Large nodules of manganese ore have been discovered on the ocean floor. The pure metal can be obtained by reduction of the oxide with sodium or by electrolysis. Manganese is more reactive that any of its neighbors on the Periodic Table. It reacts with water to produce hydrogen gas and dissolves in dilute acids to form Mn 2 .

It is a world-class chemical sedimentary deposit with an annual production of 1.8 Mt equivalent to 10 of world supply. Most of the ore is exported with some shipped to Bell Bay in Tasmania for the production of manganese alloys ( 200 000 t/year). World resources of manganese ore are large but irregularly distributed and of low-grade.

Identifying the manganese oxide minerals is a crapshoot without expensive lab equipment so generally black dendrites and crystalline occurrences are called pyrolusite while black crusts are called psilomelane. There is an acid test for manganese oxides which is that they dissolve in hydrochloric acid with the release of nasty-smelling

Manganese(IV) oxide was used in the original type of dry cell battery as an electron acceptor from zinc and is the blackish material in carbon–zinc type flashlight cells. The manganese dioxide is reduced to the manganese oxide-hydroxide MnO(OH) during discharging preventing the formation of hydrogen at the anode of the battery.
