Should nations prioritize local mineral refining even if domestic infrastructure is currently insufficient to support it?
African nations are implementing strategies to boost local mineral processing, aiming to capture more economic value from their resources. These initiatives face significant hurdles, however, as insufficient electricity generation threatens the viability of new refining projects.
Why it matters
By pivoting from raw exports to domestic refining, these countries hope to diversify their economies and improve trade balances. Success depends on securing reliable, affordable energy to compete with established global manufacturing hubs like China.
Guinea currently generates 1,000 megawatts of electricity while targeting a total capacity of up to 10,000 megawatts to support its industrial goals. Meanwhile, South Africa holds 70 percent of global chrome reserves, yet fewer than 12 of its 66 ferrochrome smelters remain operational.
The players
Guinea
Guinea is the world's largest bauxite producer and is actively seeking to expand its alumina refining capacity.
South32
South32 is a diversified mining and metals company that operates various industrial assets across the globe.
The details
Governments are utilizing export restrictions, tax incentives, and mineral deposit access to steer investors toward building essential infrastructure such as smelters and railways. Despite these efforts, the industrial transition faces setbacks, highlighted by South32 placing its Mozambique aluminium plant on care and maintenance in 2026 due to the high cost of energy.
Timeline
2008 saw power costs in South Africa begin a tenfold increase.
South32 closed its Mozambique aluminium plant in 2026.
Guinea exports surplus electricity to neighboring nations during the rainy season from April/May to November.
Guinea aims to have five alumina refineries in operation by 2030.
Market Landscape
This push for domestic processing mirrors the 2008 South African industrial power crisis, where escalating energy costs forced a sharp contraction in manufacturing output. Nations are now navigating the same structural challenge, balancing mineral wealth against the energy requirements needed to avoid similar industrial decline.
Investors and consumers may see fluctuations in metal supply chains as nations alter export policies to favor local refining. These shifts could influence the long-term pricing of aluminium and other refined minerals as processing moves closer to the point of extraction.
The takeaway
The success of mineral-rich nations depends as much on developing robust energy infrastructure as it does on implementing trade policies. Without reliable power, the ambition to capture more value from raw exports will remain constrained by high operational costs.
