Columbite and Tantalite Mining in Nigeria Explained

Columbite and tantalite — often grouped as coltan — are among Nigeria’s higher-value solid minerals. Tantalum is critical for the capacitors inside phones and laptops, so demand is tied to global electronics. Like every export mineral, it earns dollars, linking it to the naira picture across our commodity prices.

Where and how

• Deposits — found in the tin belt of the central plateau and beyond.
• Mining — frequently artisanal, alongside tin.
• Export — sold to electronics supply chains in dollars.

The electronics link

Because tantalum feeds the same devices whose prices we track — iPhones and laptops — its demand follows the global tech cycle. A Nigerian producer’s naira take depends on the dollar price and the exchange rate, the same mechanics as tin mining.
