La columbite-tantalite o columbo-tantalite (detta anche coltan) è una miscela complessa di columbite (Fe, Mn)Nb 2 O 6 e tantalite (Fe, Mn)Ta 2 O 6, due minerali della classe degli ossidi che si trovano molto raramente come termini puri.. Il termine "coltan" è usato colloquialmente in Africa per riferirsi ad una columbite-tantalite a relativamente alto tenore di tantalio.

Niobium and tantalum are chemically similar and are associated with each other in nature which makes it very difficult to separate. For many years, the separation of tantalum from niobium involved the fractional crystallization of potassium heptafluorotantalate away from potassium oxypentafluoroniobate monohydrate, this method has been supplanted by solvent extraction from fluoride-containing ...
