Coltan is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal.


We are 100% ready to supply you with good quality Coltan from African Origin. The control analyzes of the Coltan will be carried out by X-rays Fluorescence and the results of the main elements will be expressed in the form of oxides: Ta: Ta2O5, Nb: Nb2O5, Ti: TiO2, W: WO3, Sn: SnO2, Fe: Fe2O3, Al: Al2O3, Mn: MnO, U: U3O8 and L.O.I (Moisture).

The principal ore of niobium and tantalum, used mostly as an additive in steel making and in superalloys; used in metallurgy for heat-resistant alloys, rust-proofing (stainless steel) and electromagnetic superconductors. Brazil and Canada are leading producers. Used in cell phones and computer chips.


Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues
