    (from Latin columbium, an alternate name for niobium), a mineral of the columbite-tantalite group, combining complex oxides of the AB 2 O 6 type and forming the isomorphic series FeNb 2 O 6 —MnNb 2 O 6 (columbite proper) and FeTa 2 O 6 —MnTa 2 O 6 (tantalite). The columbites also include members of isomorphic series in which niobium (in weight percent) predominates over tantalum.
