Africa's Premium
Coltan Supplier
Responsibly sourced coltan from the Democratic Republic of Congo and Rwanda — processed and marketed from Nairobi to global technology markets.
Africa's Trusted
Coltan Partner
Coltan Africa is a premier mineral trading company headquartered in Nairobi, Kenya. We bridge the world's richest coltan deposits in Central Africa with global technology manufacturers who depend on tantalum for cutting-edge electronics.
Our mineral is sourced directly from certified mining operations in the Democratic Republic of Congo and Rwanda — regions that account for the majority of the world's known coltan reserves. We operate under the highest standards of responsible sourcing and compliance.
From our Nairobi hub, we leverage Kenya's world-class logistics infrastructure to deliver premium coltan concentrate to refineries and manufacturers across Asia, Europe, and North America with reliability and transparency.

What Is Coltan?
Coltan (columbite-tantalite) is a rare, metallic ore found predominantly in Central and East Africa. It is the primary commercial source of tantalum — a corrosion-resistant metal critical to modern electronics — and niobium, used in high-strength steel alloys.
Tantalum's unique properties — extreme heat resistance, excellent conductivity, and biocompatibility — make it irreplaceable in smartphones, computers, aircraft, medical implants, and the emerging clean energy sector. With global demand rising sharply, African coltan has never been more strategically valuable.
