Nigeria has signed a $1.3 billion (£1 billion) agreement with the Africa Finance Corporation to construct a major alumina refinery and fund a nationwide mineral exploration drive, in what officials describe as one of the country’s largest private-sector mining investments to date.
The deal, executed through Nigeria’s Solid Minerals Development Fund, will see the development of a refinery capable of processing one million metric tonnes of bauxite annually. It also includes the launch of a comprehensive mineral mapping programme and the creation of a dedicated investment vehicle intended to accelerate exploration projects across the country.
Announcing the agreement on Sunday, Mines Minister Dele Alake hailed the arrangement as a “landmark deal” that would help deliver President Bola Tinubu’s ambition to diversify Africa’s largest economy away from its long-standing dependence on oil revenues.
For decades, crude exports have accounted for the lion’s share of Nigeria’s foreign exchange earnings, leaving public finances exposed to swings in global energy prices. Mr Tinubu has made the revitalisation of the mining sector a central plank of his economic reform agenda, arguing that Nigeria’s untapped mineral reserves offer a route to more stable and broad-based growth.
The planned refinery will be powered by a gas-fired plant designed to generate steam and electricity for operations. At 95 per cent utilisation over a projected 20-year lifespan, the facility is expected to produce approximately 19 million tonnes of alumina, according to Mr Alake.

Alumina, a refined form of bauxite, is the critical intermediary product in the production of aluminium metal, which is used extensively in construction, transport and packaging. By processing bauxite domestically rather than exporting it in raw form, ministers hope to capture greater value within Nigeria’s borders and stimulate downstream industries.
Beyond its central role in aluminium smelting, alumina has a wide range of industrial applications. It is used in ceramics, including spark plugs and high-strength tiles capable of withstanding extreme heat. As an abrasive material, it features in sandpaper, grinding wheels and polishing compounds. In the energy sector, it serves as a catalyst support in petroleum refining.
Its chemical stability and heat resistance also make it suitable for refractory linings in high-temperature furnaces, while in healthcare it is employed in certain pharmaceutical products, including antacids. Water treatment facilities use alumina-based materials to remove impurities, underlining its importance across sectors from heavy industry to public health.
The nationwide mineral mapping initiative included in the agreement is intended to address a longstanding obstacle to investment: the lack of reliable geological data. By systematically surveying deposits of bauxite and other strategic minerals, the Government aims to provide investors with clearer information on reserves and commercial viability.
The Africa Finance Corporation, headquartered in Lagos, has positioned itself as a key backer of large-scale infrastructure and industrial projects across the continent. Its involvement is likely to be seen by officials as a vote of confidence in Nigeria’s efforts to reposition mining as a credible alternative revenue stream.
