🚨Africa’s Critical Minerals Future: Building Regional Processing Hubs
Africa’s critical minerals strategy could focus on developing specialized regional processing hubs for key minerals, with locations selected based on resource accessibility, infrastructure, energy availability, technical expertise, logistics, market access, and other economic factors.
Africa holds some of the world’s most important critical mineral resources, but its greatest opportunity may not be simply mining more. It may be processing those minerals into higher-value products before they leave the continent.
According to the United Nations Economic Commission for Africa (ECA), Africa holds approximately 30% of global reserves of critical energy-transition minerals, including cobalt, copper, graphite, lithium, manganese, nickel, platinum group metals and rare earth elements.
Africa also produces more than 77% of the world’s cobalt, 65% of manganese, 83% of platinum group metals, 21% of natural graphite and around 5.6% of nickel.
These resources place Africa at the centre of global supply chains for electric vehicles, batteries, renewable energy and energy storage.
But mineral wealth alone does not create industrial development.
The bigger question is: Can Africa move from exporting minerals to processing, refining and manufacturing higher-value products?
Moving Beyond Mine, Concentrate and Export
For decades, much of Africa’s mining industry has followed a familiar model:
Explore → Mine → Concentrate → Export
The higher-value stages often happen elsewhere.
The complete value chain can look more like:
Ore → Concentrate → Refined metal/chemical → Battery precursor → Cathode material → Battery → Recycling
Moving further along this chain can create opportunities in mineral processing, metallurgy, engineering, chemical production, laboratories, maintenance, logistics, research and recycling.
The Southern African Development Community (SADC) demonstrates why this matters. According to ECA, minerals contribute about 10% of SADC GDP, 25% of exports and 20% of government revenues, but only around 7% of direct employment.
The opportunity is therefore not simply to mine more, but to capture more value from what is already being mined.
Could Africa Become a Battery Materials Hub?
One interesting example highlighted by ECA concerns battery precursor production.
A BloombergNEF study commissioned by ECA and partners estimated that a 10,000-tonne battery precursor plant in the Democratic Republic of Congo could cost approximately US$39 million — around one-third of the cost of a comparable facility in the United States.
That suggests potential for competitive African processing.
Countries including the DRC, Zambia, Zimbabwe, Namibia and South Africa possess combinations of critical minerals, mining expertise, infrastructure and energy resources that could support regional processing and battery-material industries.
However, having minerals nearby — or even lower construction costs — does not automatically make a processing plant competitive.
Beneficiation Must Make Technical and Economic Sense
Successful mineral beneficiation in Africa depends on several fundamentals.
Energy: Mineral processing, smelting, refining and chemical conversion can be energy intensive. Unreliable or expensive electricity can quickly undermine project economics.
Water: Hydrometallurgical plants require reliable process water together with effective recycling, treatment and residue-management systems.
Reagents: Acids, alkalis, lime, flotation reagents and solvent-extraction chemicals can become major operating costs if everything must be imported over long distances.
Product quality: Producing concentrate is very different from producing battery-grade lithium carbonate, lithium hydroxide, nickel sulphate or cobalt sulphate. Downstream processing requires increasingly strict impurity control and consistent product quality.
Feed supply: A refinery needs sufficient quantities of suitable feedstock for many years. Having a mineral deposit is not enough to justify a processing plant.
These factors must be considered before deciding where beneficiation makes commercial sense.
Think Regionally About Critical Minerals
Not every African country needs its own refinery, precursor plant or battery factory.
In some cases, regional processing hubs could make more economic sense.
One country might supply copper, another cobalt, another lithium or manganese, while another provides competitive electricity, infrastructure or port access.
Regional railways, power networks, trade agreements and common investment frameworks could connect these resources into larger industrial ecosystems.
This is particularly relevant within SADC, where neighbouring countries possess complementary mineral resources.
Mining geology does not respect national borders. Perhaps mineral-processing strategy should not be constrained by them either.
Are Mineral Export Bans Enough?
Several African countries are using policy to encourage local processing. Zimbabwe, for example, has restricted exports of unprocessed lithium, while the DRC has pursued measures aimed at increasing domestic mineral processing.
Such policies may encourage investment, but export restrictions alone cannot create internationally competitive industries.
You cannot legislate good metallurgy.
Recovery matters. Energy and reagent consumption matter. Product purity, plant availability, capital cost and environmental performance matter.
Most importantly, the final product must have a customer.
Beneficiation policies therefore need to be supported by reliable infrastructure, technical skills, geological knowledge, competitive energy, access to capital and predictable regulation.
Low-Carbon Processing Could Be Africa’s Advantage
Africa could also compete through low-carbon mineral processing.
Southern Africa has significant hydroelectric, solar and other renewable-energy potential. Connecting low-carbon electricity to mines, concentrators, refineries and battery-material plants could reduce the carbon footprint of critical mineral products.
Future customers may not ask only:
How much does your nickel cost?
They may increasingly ask:
How much carbon was emitted producing that tonne of nickel?
The same applies to lithium, cobalt, copper, manganese and graphite.
Developing competitive, low-carbon processing capacity could therefore become an important African advantage.
From Mineral Wealth to Metallurgical Capability
Africa’s critical minerals opportunity should ultimately be measured by more than tonnes mined or dollars exported.
The real indicators will be how much processing takes place locally, how many metallurgists and technicians are trained, how much technology and expertise are developed, how many local businesses enter the supply chain, and how much value remains within African economies.
Africa certainly has the critical minerals.
The harder challenge is building the metallurgical capability, infrastructure, energy systems, skills and investment environment required to transform them into higher-value products.
If that happens, the critical minerals boom could become more than another cycle of resource extraction.
It could help build a broader African mineral-processing and manufacturing industry.
