Tantalite & Coltan

Tantalite concentrate at 25–35% Ta2O5 is refined into K-salt and onward to capacitor-grade tantalum powder. Capacitor manufacturers in Japan, China and the US set the spec standards. Origin documentation under Dodd-Frank Section 1502 and OECD Due Diligence Guidance is non-negotiable for any end-user audited by a major listed company. We supply CMRT statements on request and trace through RMI-conformant smelter lists where the downstream requires it.
