    Definition dull metallic mineral which is a combination of columbite and tantalite and which is refined to produce tantalum Reference "Oxford Dictionaries > Definition of coltan in English, http://www.oxforddictionaries.com/definition/english/coltan [2.10.2015]"
    Comment "It is found in major quantities in the eastern areas of Congo. When refined, it becomes metallic tantalum, a heat-resistant powder that can hold a high electrical charge. These properties make it a vital element in creating capacitors, the electronic elements that control current flow inside miniature circuit boards. Tantalum capacitors are used in almost all cell phones, laptops, pagers and many other electronics.‘What is Coltan?’ abc News, http://abcnews.go.com/Nightline/story?id=128631&page=1 [2.10.2015]"

    Definition "La ""colombo-tantalite"" (coltan en abrégé) est un mélange de minerais rares, un sous-produit des mines d'étain assez facile à extraire. On l'utilise surtout pour fabriquer les ""condensateurs à tête d'épingle"", un composant qui permet de réguler la tension électrique dans la plupart des téléphones et des ordinateurs portables ainsi que dans certaines consoles de jeu."
