Africa sits atop a treasure trove of minerals, from gold and diamonds to cobalt and lithium, which fuel global industries. The mining sector contributes an estimated $400 billion annually to the continent’s GDP, accounting for nearly 10% of total employment in many countries. Africa produces over 70% of the world’s platinum, 60% of its cobalt, and 50% of its manganese, making it indispensable to industries ranging from electric vehicles to technology and jewellery. However, this prosperity comes at a steep cost. The environmental consequences—deforestation, water contamination, and carbon emissions—cast a long shadow over the industry’s economic promise.
Sustainable mining in Africa is no longer just an option but a necessity. Governments, industry stakeholders, and environmental advocates are locked in a high-stakes balancing act: Can Africa extract its mineral wealth without mortgaging its environmental future?

The Cost of Extraction
The Democratic Republic of Congo (DRC) holds 70% of the world’s cobalt reserves, a critical mineral for electric vehicle (EV) batteries. In 2023, the global cobalt market was valued at $8.5 billion, with demand expected to triple by 2030. Meanwhile, Ghana and South Africa remain leading gold producers, with Ghana exporting over four million ounces annually, generating $5 billion in revenue. South Africa, once the world’s largest gold producer, now mines 110 metric tonnes annually, contributing $7 billion to its economy.
However, these financial windfalls are counterbalanced by severe environmental degradation. Nigeria’s artisanal gold mining sector, worth $1.2 billion, has led to widespread lead poisoning, affecting over 17,000 children. The Zambian Copperbelt, producing over 800,000 metric tonnes of copper per year, struggles with acid mine drainage contaminating water supplies. In Madagascar, the rapid expansion of ilmenite and graphite mining—integral for lithium-ion batteries—has caused an 80% loss of natural forests in key mining areas.
Africa’s lithium reserves, primarily in Zimbabwe, Namibia, and the DRC, attracted over $1.5 billion in investments in 2023 alone, driven by global demand for EV batteries. However, lithium mining is extremely water-intensive, requiring 2.2 million litres of water to produce just one tonne of lithium. This raises concerns about water scarcity in already drought-prone regions.
Can the Green and the Gold Coexist?
Mining and sustainability may seem like strange bedfellows, yet innovative solutions are emerging to reconcile these forces. Circular economy principles are reshaping how minerals are extracted and reused. Companies are investing in recycling and waste recovery to minimise new extractions. Rwanda, which exports $800 million in tin, tantalum, and tungsten (3Ts) annually, has implemented strict environmental guidelines requiring mining companies to invest at least 2% of their revenue into land rehabilitation.
Technology is also playing a role. South Africa’s Anglo American Platinum has developed hydrogen-powered mining trucks, cutting carbon emissions by up to 80%. In Ghana, drone technology is being deployed for precision mining, reducing unnecessary land disturbances. AI-driven mapping techniques are being tested in Botswana to predict mineral deposits with minimal ground disruption.
In Namibia, the world’s first fully solar-powered uranium mine, Husab, has reduced its carbon footprint by over 50%. Similarly, Tanzania’s Barrick Gold mine is implementing zero-discharge water recycling, ensuring that 100% of its used water is treated and reused instead of contaminating local sources.
The Policy Compass
Governments and international organisations are enforcing stricter regulations to ensure sustainable mining. The African Mining Vision (AMV), endorsed by the African Union, aims to promote transparent governance, fair taxation, and ecological responsibility. The implementation of Environmental, Social, and Governance (ESG) standards is pushing companies to disclose their sustainability efforts.
Yet, enforcement remains a challenge. In 2023, over 50 illegal mines were shut down in Zimbabwe, but thousands remain unregulated. Similarly, in Tanzania, only 30% of small-scale miners adhere to environmental safety standards, leaving vast tracts of land permanently damaged. The DRC, despite its mineral wealth, loses an estimated $1.3 billion annually to illegal mining activities that operate without environmental oversight.
Some countries have set a positive example. Botswana reinvests 25% of its diamond revenues into infrastructure, education, and environmental conservation. In contrast, Nigeria’s lax regulatory framework has resulted in unchecked lead poisoning cases due to illegal gold mining, costing the government over $150 million in remediation efforts since 2010.
Striking the Balance
Africa’s future in mining does not have to be a choice between economic growth and environmental destruction. By adopting greener technologies, enforcing stricter policies, and promoting local community engagement, the industry can ensure long-term sustainability. Countries like Botswana showcase that responsible mining is achievable.
International pressure is also mounting. The European Union’s Critical Raw Materials Act, passed in 2023, mandates that all imported minerals adhere to strict sustainability guidelines, a move that could shift African mining practices towards greener alternatives. China, Africa’s largest mining investor, has pledged $10 billion in funding for sustainable mining projects across the continent by 2030.
The path forward requires a unified effort from governments, investors, and local communities. If the continent can successfully navigate this terrain, it stands to emerge not just as a mining powerhouse but also as a beacon of sustainable resource management. The choice is clear: Africa can either mine its way to prosperity while preserving its environment or risk depleting both its natural wealth and future economic potential.
