Africa Pivots to Capture Critical Minerals Value Through Processing and Infrastructure

Africa holds roughly a third of the world's mineral reserves but captures only a tenth of global mining revenues. That gap—between what the continent possesses and what it actually earns—is the story driving a fundamental restructuring of how African nations approach their most valuable resource.

The continent already supplies the world with copper, cobalt, and manganese in significant quantities. Yet for centuries, the extraction model has remained largely unchanged: foreign companies and governments pull raw materials from African soil, process them elsewhere, and keep most of the profit. Colonial trade patterns, established in the late 19th and early 20th centuries, created a system of unequal exchange that persists today. As Western nations and China compete fiercely for the metals needed to power electric vehicles, batteries, renewable energy systems, and artificial intelligence infrastructure, African governments have recognized an opening to break that pattern.

The strategy is straightforward in concept but demanding in execution: process minerals locally rather than shipping them raw. Indonesia demonstrated the model's potential. In 2020, it banned nickel ore exports, compelling mining companies to build processing capacity within the country. The result was transformation—Indonesia became a global leader in refined nickel products and nickel sulfate for battery makers. Zimbabwe, Guinea, and the Democratic Republic of the Congo have adopted similar restrictions on lithium, bauxite, and cobalt exports respectively, each betting that forced investment in local facilities will capture more value at home.

But building a viable processing industry requires far more than ore in the ground. Smelting and refining operations need stable electricity, functioning roads and railways, ports, logistics networks, technical expertise, and governments that maintain predictable policies. For industries operating on thin margins, these infrastructure elements can matter more than the mineral reserves themselves. Angola is constructing an aluminum plant at Barra do Dande despite having no bauxite reserves and no capacity to produce alumina—the intermediate material smelting requires. The project works because of a deep-water port, a free economic zone, shared infrastructure, business-friendly conditions, and reliable power.

The Lobito Corridor represents the continent's most ambitious attempt to reshape mineral trade geography. This 1,800-kilometer infrastructure project connects Central Africa's Copperbelt through upgraded and new railway lines to the Atlantic port of Lobito in Angola. Currently, much of the region's copper and cobalt travels via the TAZARA railway—built by China in the 1970s—to the Tanzanian port of Dar es Salaam, then onward to China. The journey takes more than a month. Lobito could cut that to roughly one week, reducing investor risk and opening new possibilities. The United States and European countries are backing the corridor heavily, viewing it as a counterweight to Chinese dominance in regional mineral flows. China responded by pledging $1.4 billion to modernize TAZARA, turning the two routes into genuine competitors that could give Congo and Zambia more negotiating power.

The corridor is designed as more than a mining highway. Agricultural, industrial, and technology hubs are planned along its route. European partners are investing in what they call soft infrastructure—trade facilitation, vocational training, technical skills development, and local job creation. Angola is already moving agricultural products through the system; last November it exported avocados to Europe for the first time, using a trade logistics platform and a €50 million European investment program in agricultural value chains. This integrated approach matters because processing plants alone cannot transform an economy if they operate as isolated export enclaves with no connection to surrounding communities. The Democratic Republic of the Congo already produces refined copper but ships nearly all of it to China for conversion into finished goods. Real development requires manufacturing as close as possible to extraction.

The most intractable challenge lies in formalizing artisanal and small-scale mining. An estimated 10 million people work directly in these operations, with millions more depending on them indirectly. In rural areas with few other employment options, small collective mines remain a primary income source. The work is frequently dangerous—women and children participate in extraction, fatalities occur regularly, and environmental damage is severe. Colonial-era laws that criminalized such operations pushed millions of workers into the shadows for decades, costing governments revenue and creating an ethical minefield for Western companies wary of purchasing metals of unclear origin. In conflict zones, particularly in eastern Congo and parts of the Sahel, armed groups control mines and force workers to labor there.

The Democratic Republic of the Congo, long accused of supplying conflict cobalt, is attempting the most ambitious formalization effort. Previous attempts failed to produce results, but a new program launched jointly with Eurasian Resources Group combines export quotas on cobalt with expanded powers for the state regulator, the General Cobalt Enterprise. For Western nations seeking Congolese cobalt and trying to reduce dependence on Chinese operators, cooperation with small-scale miners may be essential—but only if those raw materials come with guarantees of freedom from forced labor, human rights abuses, and armed group involvement. Bringing traditional miners into the legal economy serves governments, businesses, and workers simultaneously. For Africa, it could become one of the most significant steps toward dismantling the historic extraction model and building long-term development on the foundation of mineral wealth.
