Tantalite contains some niobium, with the mineral being referred to as niobite or columbite when the niobium content is greater than that of tantalum. Indeed, until the discovery of the world's pyrochlore deposits in the 1950s, niobium was a byproduct of tantalum mining, with increasing demand ensuring that it was highly valued and highly ...

(from Latin columbium, an alternate name for niobium), a mineral of the columbitetantalite 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.
Coltan is short for Columbitetantalite – a black tarlike mineral found in major quantities in the Congo. The Congo possesses 80 percent of the world's coltan. When coltan is refined it becomes a heat resistant powder that can hold a high electric charge. The properties of refined coltan is a vital element in creating devices that store ...
