Production, trade flows, pricing and policy risk across the African continent: the 150-page market report on the mineral behind the world’s capacitors.

Tantalum makes the tiny, reliable capacitors inside smartphones, cars, medical devices and the servers that power artificial intelligence. Niobium makes stronger, lighter steel. The world mines only about 2,500 tonnes of tantalum a year, and most of it is dug by hand in Africa.
That makes coltan one of the most strategic and least transparent markets in the world. In 2026, deadly landslides at the Rubaya mine in the eastern DRC, a site estimated to supply 15–20% of world coltan, sent tantalite prices to their highest level in over twenty years.
This report brings together official data, market reporting and first-hand knowledge from Nigeria’s columbite belt to explain who supplies coltan, how it moves, how it is priced, what can disrupt it and where the market is heading.

Each chapter opens with its key findings, so you can scan the conclusions first and go into the detail when you need it.
Uses, demand drivers, global supply and the processing map.
Country-by-country analysis of every significant producer.
From pit to smelter, China’s dependence, and how coltan is priced.
Regulation, traceability, geopolitics and country risk.
Demand and supply outlooks, scenarios and implications.
Deep dives into the issues that cut across the market.
After five years in a narrow range, tantalite prices nearly doubled in the first quarter of 2026. Chapter 18 sets out the full timeline, explains why such a small market moves so violently, and shows how the shock passed through to metal, powder and scrap.
Part V then asks the question every buyer and investor is asking: what next? Three scenarios, each with signposts to watch, take the outlook to 2030.
