Premium Coltan (Tantalite) & Niobium Supply

We supply high-quality coltan (tantalite) and niobium sourced from certified mining regions across Central and East Africa. Our sourcing network ensures consistent Ta/Nb ratios, verified mineral composition, transparent documentation, and reliable export solutions for global refiners, capacitor manufacturers, alloy producers, and technology industries.

Coltan (Tantalite) & Niobium

Our Coltan & Niobium division delivers premium tantalum-rich ore and niobium-bearing minerals suitable for refining into capacitors, superalloys, aerospace components, batteries, and advanced electronics. We source from verified concessions in the Democratic Republic of Congo (DRC), Rwanda, Burundi, and Tanzania, operating under strict compliance and ethical guidelines. Each shipment undergoes comprehensive mineral analysis, grading, and professional export handling to meet the demands of global high-tech and industrial customers.

Our Coltan & Nobium Supply Process

We follow a transparent and structured process to ensure quality, consistency, and reliability for every shipment. From mineral sampling to documentation and international shipping, our workflow ensures full traceability and compliance with global standards.

[ 1 ]

Quality Verification & Assessment

We evaluate coltan and niobium ore using certified laboratory methods to determine Ta₂O₅ and Nb₂O₅ content, alongside impurity levels such as Fe, Ti, Sn, and Si. Each batch is accompanied by SGS/Intertek analysis, mine-origin verification, and chain-of-custody documentation to ensure authenticity and quality.

Customized Supply Planning & Documentation

We tailor supply schedules based on your refining or industrial needs—whether for high-grade Ta refining or mixed Ta/Nb processing. All documentation is provided, including assay certificates, export permits, mining licenses, shipping documentation, customs clearances, and CoC/traceability records following OECD standards.
