Abstract: 

Manganese ore coming from Corumbá, Mato Grosso do Sul, Brazil was investigated to ascertain its mineral composition. Chemical analysis, X-ray diffraction along with energy dispersive analysis allowed establishing that the mineral is a mixture of Mn2+Mn3+2 and Mn4+O2 oxides, hausmannite and pyrolusite which are present as major and minor phases respectively. It is assumed that the mineral also contains neotocite, a manganese-iron silicate (Mn+20.75, Fe2+0.25) SiO3 H2O that is present in the amorphous state and cannot be detected by X-ray technique.
