Wolframite, cassiterite and coltan from Burundi, plus beryl and lithium under our export licence. Every lot is tested, ITSCI-tagged and shipped with full traceability and export documentation.
Tungsten ore
Wolframite is the main ore of tungsten – the metal with the highest melting point of all elements (3,422 °C), used in cemented carbides, superalloys, welding electrodes and radiation shielding. Wolframite is our lead export: we supply concentrate from Burundi’s tungsten belt and are open to long-term offtake agreements.
Metal
Tungsten (W)
Grade basis
WO3 content, confirmed by assay for every lot
Documentation
Analysis certificate, ITSCI tags, ICGLR export certificate
Availability
Open for offtake agreements
Tin ore
Cassiterite is the most important source of tin, used in electronics solders, tinplate and chemicals. Its high density and resistance to weathering let it concentrate in alluvial deposits. We source cassiterite concentrate from licensed Burundian operators; every lot is tagged and documented under ITSCI.
Metal
Tin (Sn)
Grade basis
Sn content, confirmed by assay for every lot
Documentation
Analysis certificate, ITSCI tags, ICGLR export certificate
Tantalum ore
Coltan (columbite-tantalite) is the main source of tantalum, used in capacitors for electronics and in superalloys. Coltan on the international market generally contains a minimum of 30% Ta2O5, while lower-grade material with a minimum of 20% Ta2O5 may also be of interest. The payable value is based on the Ta2O5 content alone; Nb2O5 is generally not paid.
Metal
Tantalum (Ta)
Typical market grade
Min. 30% Ta2O5 (min. 20% for lower-grade material)
Documentation
Ta2O5 assay certificate, ITSCI tags, ICGLR export certificate
