Nsutite
Nsutite is a manganese oxidemineral with formula: (Mn1−xMnxO2-2x(OH)2x where x = 0.06–0.07). 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.
