Nsutite is a manganese oxide mineral with formula: (Mn⁴⁺_1−xMn²⁺_xO_2-2x(OH)_2x where x = 0.06–0.07).http://www.webmineral.com/data/Nsutite.shtml Webmineral data It is found in most large manganese deposits and was first discovered in Nsuta, Ghana. Since then, it has been found worldwide. Nsutite is a dull mineral with a hardness of 6.5–8.5 and an average specific gravity of 4.45. Nsutite has been used as a cathode in zinc–carbon batteries, but synthetic manganese oxide is gradually replacing it.
