Tantalum–Niobium Oxide
Tantalite
(Fe,Mn)(Ta,Nb)₂O₆
Tantalite is the principal ore of tantalum — the metal behind the compact, high-reliability capacitors in almost every phone, laptop and engine control unit. It occurs across the same Nasarawa, Kogi, Plateau, Ekiti and Oyo pegmatite belt we already work for lithium, usually alongside columbite as the columbite–tantalite series. It is exceptionally dense, which is what makes gravity recovery effective, and it is priced on contained Ta₂O₅ rather than on tonnage.
Our plan to source it
Spec lock
You confirm target Ta₂O₅ grade, tonnage and destination. Because tantalite prices on contained metal, we fix the grade basis before anything else.
Traceable source selection
We go to holders inside the pegmatite belt who can evidence the origin of their material, since tantalum is a 3TG mineral and an untraceable lot is unsellable to a conformant smelter.
Chain-of-custody tagging
Material is tagged at the point of aggregation so the lot carries documented origin from mine site through to export.
Gravity upgrading
Concentrate is upgraded on jigs and tables, exploiting tantalite's very high density, then magnetically cleaned to lift Ta₂O₅ toward your target.
Assay & radiometric screening
Lab assay for Ta₂O₅ and Nb₂O₅, plus radiometric screening for uranium and thorium, which govern how the lot can legally be shipped.
Due diligence pack & export
We assemble the origin documentation your smelter's audit requires, then handle export licensing and freight to your port.
Regulatory handling — Tantalum is a 3TG conflict mineral. Lots ship with documented chain of custody so buyers can satisfy OECD due-diligence and downstream smelter audit requirements.
