Guinea is pushing ahead with plans to expand domestic mineral processing, with state-owned Nimba Mining Company (NMC) announcing preparations for a new alumina refinery expected to come online around 2030, officials said.
The project would become the country’s fourth alumina refinery initiative and is part of a broader government strategy to move away from exporting raw bauxite and instead capture more value locally in the mining sector.
Guinea is the world’s largest exporter of bauxite but currently operates only one alumina refinery the Friguia plant run by Russia’s Rusal leaving most of its ore exported for processing abroad.
According to NMC chief executive Patrice L’Huillier, feasibility studies for the new refinery are already underway and are expected to last about 18 months, followed by a construction period of two to three years.
The planned facility would have an annual production capacity of around one million tonnes of alumina, an intermediate product used in aluminum production and significantly more valuable than raw bauxite.

L’Huillier said the project builds on earlier studies conducted in the early 2010s and reflects a renewed push by both the company and the Guinean government to advance industrialization in the mining sector.
“This is a long-standing project for which initial studies had already been conducted and whose site has already been identified. Our ambition now is to move into a concrete execution phase,” he said in comments published by Ecofin Agency.
Two other large-scale alumina refinery projects are already under development in Guinea, led by China’s State Power Investment Corporation (SPIC) and the Winning Consortium Alumina Guinea (WCAG), with combined investment exceeding $2 billion.

Industry data cited by officials show that alumina currently trades at roughly $346 per tonne, compared with about $67.50 per tonne for Guinean bauxite exported to China, underscoring the government’s push for value addition.
The move comes as Guinea seeks to restructure its mining industry to retain more economic benefit from its vast mineral reserves. The country exported about 182 million tonnes of bauxite in 2025 alone, cementing its position as the global leader in supply.
Authorities say increasing local refining capacity could significantly boost export earnings, create jobs and reduce dependence on raw commodity shipments.
However, officials acknowledge that the transition is complex, requiring large-scale investment, reliable infrastructure and stable regulatory conditions to support long-term industrial operations.
NMC also faces operational challenges as it restarts mining activities following a suspension linked to a dispute between the Guinean state and former operator Emirates Global Aluminium (EGA), which halted production for over a year before resuming in December 2025.
Analysts say Guinea’s refinery ambitions reflect a wider trend across resource-rich African countries seeking to move up the value chain rather than remain dependent on raw material exports.

Still, the success of the strategy will depend on whether planned projects can overcome financing constraints, technical hurdles and infrastructure gaps, particularly in energy supply and transport networks.
If completed on schedule, the new refinery would mark another step toward reshaping Guinea’s mining sector into a more industrialized and domestically integrated industry, officials say.
