Geographic Minerals



Cattierite (CoS2) is a cobalt sulfide mineral found in the Democratic Republic of Congo. It is a mineral consisting of cobalt sulfide and belonging to the pyrite group. It was discovered together with the nickel sulfide vaesite by Johannes F. Vaes, a Belgian mineralogist and named after Felicien Cattier, Chairman of the Board, Union Miniere du Haut Katanga.

The mineral belongs to the pyrite group, in which all minerals share the same building principle. The metal in the oxidation state +2 forms a sodium chloride structure together with the anion S22−. This formalism recognizes that the sulfur atoms in pyrite occur in pairs with clear S-S bonds.
