Export Bans or Industrial Strategy? Africa’s Critical Minerals Dilemma in the Race for Beneficiation
This question has gained urgency as global demand for lithium, cobalt, manganese, and rare earth elements accelerates under the energy transition. African countries, many of which hold significant reserves of these minerals, are seeking to reposition themselves within global supply chains.
Yet they face a familiar structural constraint: raw commodities continue to be exported, while higher-value processing, industrial capacity and technological capabilities remain concentrated elsewhere, particularly in countries that dominate refining.
In response, policymakers are increasingly turning to export controls and beneficiation mandates as instruments to capture greater value domestically. However, these interventions introduce clear trade-offs. While they may support long-term industrialisation goals, they also risk disrupting investment flows, triggering disputes with investors and exposing institutional weaknesses.
The Economic Trade-Off
At the core of critical minerals policy lies a temporal trade-off between short-term stability and long-term industrial transformation.
Export restrictions are intended to retain more value within domestic economies by forcing upstream linkages, encouraging local processing and generating employment. In theory, they can help disrupt patterns of extractive dependence, where resource-rich economies export raw materials while importing finished goods.
However, these benefits are neither immediate nor guaranteed.
Restrictive policies often impose short-term costs, including reduced export revenues, increased investor uncertainty and potential retaliation from trading partners. For countries that rely heavily on mineral exports for fiscal stability, these risks are significant.
Moreover, mineral processing is both capital-intensive and infrastructure-dependent. It requires reliable electricity, transport networks, water supply and specialised technical expertise, all of which remain constrained in many African contexts. Without these enabling conditions, export restrictions alone are unlikely to generate viable processing industries.
This creates a sequencing challenge: how to transition from raw material exports to industrial processing without triggering capital flight or undermining economic stability.
Comparative Policy Signals Across Africa
Recent experience across major mineral-producing countries illustrates how different policy approaches are unfolding in practice.
Zimbabwe: Phased Transition
Zimbabwe was among the first African countries to impose restrictions on lithium exports, banning the export of unprocessed lithium ore in 2022. The policy has since evolved into a phased approach, with a planned ban on lithium concentrates by 2027.
This sequencing reflects a recognition that processing capacity requires time to develop. The transition period has enabled significant investment in processing infrastructure, largely from Chinese firms, with investments exceeding $1 billion in lithium projects.
However, while Zimbabwe has expanded intermediate processing capacity, much of the output continues to be exported for further refinement abroad. This highlights both the potential and the limits of export restrictions in driving full value chain development.
Democratic Republic of Congo: Quotas and Governance Constraints
The DRC’s experience with cobalt export controls illustrates the challenges of implementation.
At the same time, the absence of domestic refining capacity means that cobalt continues to be exported in intermediate forms. Without sufficient infrastructure and institutional capacity, export controls risk reshaping trade flows rather than fundamentally altering value chains.
The DRC case underscores a key lesson: without credible enforcement and processing capacity, regulatory interventions can introduce inefficiencies without achieving structural transformation.
Tanzania: Integrated Strategy
Tanzania’s approach represents a broader and more integrated model.
The government has outlined a long-term strategy that combines processing ambitions with complementary reforms, including licensing reviews, small-scale miner formalisation and the proposed establishment of a sovereign wealth fund. A national refinery is targeted for completion by 2030.
This approach recognises that beneficiation is not a standalone policy, but part of a wider industrial ecosystem. By aligning timelines with infrastructure development and institutional capacity, Tanzania is attempting to manage the transition more systematically.
Namibia: Measured Positioning
Namibia has taken a more cautious approach, signalling interest in beneficiation while maintaining regulatory predictability.
Despite significant mineral potential, infrastructure constraints, particularly high electricity costs, limit immediate processing feasibility. As a result, Namibia appears to be balancing long-term value addition objectives with the need to remain an attractive investment destination.
This measured approach reflects a broader strategic consideration: countries with a smaller market share or a later entry into global supply chains may need to prioritise stability over immediate restrictions.
Where Policies Succeed and Fail
Comparative experience suggests that export restrictions alone are insufficient to drive sustainable industrialisation.
In the DRC, export controls have not resulted in meaningful downstream processing due to limited infrastructure and weak enforcement systems. Instead, they have altered trade routes and introduced governance risks, including opportunities for rent-seeking.
Zimbabwe’s phased approach has produced more tangible results, particularly in attracting investment into processing facilities. However, the country has yet to capture higher levels of value addition, as refined materials continue to be processed further abroad.
Tanzania’s strategy reflects an understanding of these limitations. By aligning beneficiation goals with infrastructure development, institutional reform and long-term planning, it attempts to address the structural constraints that often undermine export control policies.
These cases point to a consistent insight: policy outcomes are shaped not by regulatory ambition alone, but by alignment between policy design, infrastructure readiness and institutional capacity.
Why Sequencing Matters
The evidence points to sequencing as a central determinant of policy effectiveness.
Phased approaches provide a regulatory pathway that allows investors to plan and allocate capital over time. Zimbabwe’s transition from a raw ore ban in 2022 to a planned concentrate ban in 2027 demonstrates how timelines can signal policy direction while accommodating implementation realities.
Infrastructure readiness is equally critical. Processing minerals requires reliable energy, transport systems and industrial facilities, and without these, regulatory mandates risk becoming unenforceable or counterproductive.
Regulatory predictability also plays a decisive role. Sudden policy shifts or discretionary frameworks can deter investment, particularly in capital-intensive sectors with long payback periods. Transparent and time-bound policies are more likely to attract sustained investment.
Finally, regional coordination is emerging as an important factor. Fragmented national approaches may limit economies of scale and reduce bargaining power in global markets. Frameworks such as the African Continental Free Trade Area offer potential pathways for coordination, though they remain underutilised in the minerals sector.
Structural Risks and Strategic Implications
Several structural risks are becoming apparent as countries pursue beneficiation strategies.
Regulatory fragmentation is a growing concern. Divergent national approaches ranging from outright bans to quota systems and long-term industrial strategies may increase transaction costs and complicate cross-border investment.
Governance capacity remains uneven. Where enforcement systems are weak or discretionary, policies may create opportunities for rent-seeking rather than industrial development.
Market positioning also matters. Countries with significant global market share, such as the DRC in cobalt, possess greater leverage than smaller producers. For newer entrants, restrictive policies may deter investment without delivering meaningful gains.
These dynamics suggest that beneficiation strategies must be context-specific. A uniform approach is unlikely to succeed across diverse economic and institutional environments.
Ultimately, the effectiveness of Africa’s critical minerals policies will depend on the ability to balance ambition with implementation. Countries that align industrial objectives with infrastructure development, regulatory clarity and coordinated action are more likely to capture value from their mineral endowments. Those that rely on restrictive measures without supporting systems risk disrupting investment while leaving underlying structural constraints unchanged.
