    Tantalum Mineralisation in AustraliaJORC Ore ReservesIdentified ResourcesProductionWorld RankingIndustry DevelopmentsCitationTantalum shares many of its properties with niobium (Nb), with which it is commonly found. This close association has led to use of the 'coltan' terminology, short for columbite-tantalites, reflecting the niobium-dominant (columbite)2and tantalum-dominant (tantalite) end-members of this oxide mineral series (see text box below). Tantalite is a dominant ore mineral of tantalum and is most commonly found within rare-metal granites and pegmatites, which are suggested to account for more than three-quarters of current
