July 2025 – Harare/Windhoek – A sweeping policy shift is reshaping Africa’s mineral economy, as nearly half of the continent’s nations—including Zimbabwe, Namibia, and the Democratic Republic of Congo—move to restrict or ban the export of unprocessed critical minerals such as lithium, cobalt, nickel, and graphite. The strategic pivot reflects a growing consensus: the continent must no longer be relegated to the role of raw materials supplier in the global clean energy transition.
From Extraction to Transformation
Governments across Africa are increasingly linking mining concessions to domestic beneficiation mandates—requiring that some or all of a mineral’s processing take place within national borders. These policies are driven by the pursuit of industrial value capture, job creation, and economic sovereignty.
In Zimbabwe, one of the region’s fastest-growing lithium exporters, the impact is already visible. The country’s lithium export revenues soared from $70 million in 2022 to over $600 million in 2023, largely due to new partnerships with Chinese and Australian firms investing in domestic processing plants. Similar restrictions in Namibia now target exports of unrefined lithium and rare earths, pushing foreign investors toward local joint ventures.
A New Investment Playbook
For international mining firms and battery manufacturers, Africa’s policy reset demands a recalibrated strategy. Access to key minerals increasingly hinges on delivering value locally—through processing facilities, technology transfers, and workforce development.
The traditional model of extracting and exporting raw materials is becoming commercially and politically unviable. Instead, investors must now build integrated supply chains within host countries: leaching plants, refining hubs, and cathode material production lines. In parallel, host governments are offering incentives—such as tax breaks and fast-track permits—to companies that commit to local value addition.
What’s Driving the Shift?
Three core trends are accelerating Africa’s mineral nationalism:
-
Global decarbonization: The race to electrify transport and expand renewable energy has turned lithium, cobalt, and nickel into geopolitical resources. African states want more leverage in this global transition.
-
Inflation of raw material prices: A surge in demand for critical minerals has inflated margins for downstream processors, not raw exporters.
-
Domestic political pressures: Leaders across the continent face pressure to translate natural wealth into jobs, infrastructure, and industrial base growth.
Winners and Risks
Countries like Zimbabwe and Namibia, which moved early to mandate local processing, are beginning to climb the value chain—generating more revenue per tonne of mineral and attracting infrastructure investments in logistics and energy.
But risks remain. Inadequate power grids, infrastructure gaps, and regulatory uncertainty can deter investment. In some countries, sudden policy shifts—such as blanket bans without transition plans—have disrupted existing mining operations and sparked investor pushback.
Global Supply Chains at a Crossroads
Africa’s assertiveness is reshaping global supply chains for electric vehicles, solar panels, and advanced electronics. China, already a dominant player in processing, has adapted quickly—building joint ventures in Zambia, Zimbabwe, and DRC. Western firms, by contrast, have lagged in aligning commercial interests with local policy demands.
As more African nations consider similar beneficiation laws, the pressure is growing on foreign players to think beyond extraction and invest in inclusive, sustainable industrial ecosystems.
Bottom Line
Africa’s mineral-rich countries are rewriting the rules of engagement in the global energy economy. For investors, the message is clear: access to critical minerals now depends on creating shared value, not just extracting raw ones. In this new paradigm, local processing is no longer optional—it’s the cost of entry.
