At the Group of Seven summit in Evian-les-Bains, France, on June 17, Kenyan President William Ruto said Kenya was close to a critical minerals agreement with the United States. The bigger story was not the handshake-in-waiting; those are easy to come by. It was Kenya’s condition: its rare earths, lithium, graphite, copper, nickel and niobium should be refined and processed at home, not simply dug up and shipped out.

That is the heart of Africa’s critical minerals debate. Governments are trying to change a familiar bargain in which the continent supplies raw materials, then buys back expensive finished goods. It has never been a fair deal.

Why African governments want processing at home

Kenya is not acting alone. Across the continent, governments are pushing to keep more value from natural resources before those resources enter global markets.

Namibia has banned exports of unprocessed lithium, cobalt, manganese, graphite and rare earths. Mali is building a gold refinery with capacity of 200 tonnes a year and is requiring more local refining. Ghana plans to start buying 30 percent of large-scale gold production from July 2026, with the goal of strengthening domestic refining and reserves.

This is about more than lithium or rare earths. African governments are increasingly saying that minerals, metals and other resources should help build industries at home before generating profits elsewhere. That demand has been made for decades. The difference now is that more countries are trying to enforce it.

Why the timing matters for global supply chains

Kenya’s position comes as demand for minerals used in electric vehicles, battery storage, renewable energy systems and advanced manufacturing is rising fast. Lithium consumption increased by almost 30 percent in 2024. The International Energy Agency projects that lithium use will rise fivefold by 2040, while demand for graphite and nickel will roughly double.

This boom is different from earlier commodity cycles because supply cannot expand quickly. New mines often take well over a decade to move from discovery to permits, development and first production. Demand, meanwhile, is not slowing down.

Under its Stated Policies Scenario, the International Energy Agency estimates that announced mining projects will leave lithium supply 40 percent below projected demand by 2035. That gives countries with mineral deposits more leverage. For African governments, it creates room to push for local processing, technology transfer and industrial investment, not just extraction royalties and another photo-op.

Where the real money is made

Mining is only the first stage. The largest gains come later, when minerals are refined, processed and turned into materials, parts and finished products that sell for far more than raw ore.

United Nations data shows how sharply value rises along the lithium-ion battery chain. In 2022:

  • Global exports of lithium ore and brine were worth about $20 billion.
  • Battery materials generated $51 billion.
  • Cell components and battery packs generated $106 billion.
  • Electric vehicles generated $135 billion.

Africa’s challenge is to move further along that chain. Each additional stage completed on the continent means more income, more skilled jobs and more technology staying closer to the source of the minerals.

Refining is only the beginning. It opens the door to the broader capabilities that separate manufacturing economies from extractive ones.

What beneficiation can build beyond mines

Beneficiation means processing raw materials into higher-value products before export. Around refinery clusters, other industries can grow: engineering firms, chemical producers, equipment makers, laboratories and specialist suppliers.

That is why the demand is not just about national pride, though that is part of it. It is about building productive capacity. A country that learns to process minerals can also build supplier networks, technical skills and manufacturing systems that support future industries.

Taiwan’s industrial development offers a useful broader lesson. With sustained policy, skilled workers and strong supplier networks, capabilities built in one generation can support higher-value industries in the next. Africa’s mineral producers want to grab that advantage before the next phase of the global energy economy is locked in elsewhere.

The politics of supply chains have started to work in their favor. China is the dominant refiner for 19 of the 20 strategic minerals tracked by the International Energy Agency. For copper, lithium, nickel, cobalt, graphite and rare earths, the top three refining countries control 86 percent of processed output. That concentration makes alternative processing hubs more valuable.

The history African leaders are trying not to repeat

Africa has seen resource booms before. Gold, diamonds, copper and oil generated billions of dollars in exports, but many resource-rich economies remained dependent on selling raw commodities instead of manufacturing higher-value products.

The colonial economy was built around outward flows. In what is now Zambia, copper from Nkana, Mufulira and Nchanga moved through Ndola and along rail lines to Beira, the Mozambican port that connected the Copperbelt to overseas smelters and factories. In the Gold Coast, present-day Ghana, cocoa from Kumasi travelled by rail to Sekondi and later Takoradi before feeding Britain’s chocolate industry.

Today’s export restrictions, refining mandates and beneficiation policies are attempts to interrupt that old pattern. The goal is to make sure industries built around African minerals take root in Africa, not just in the countries that buy the raw material.

What Africa could gain from moving up the chain

The payoff is not just better trade statistics. It is the creation of industries that last beyond a single mining cycle.

Research by Publish What You Pay suggests that expanding higher-value mineral processing across Africa could:

  • Generate an additional $32 billion in annual exports.
  • Add up to $24 billion to the continent’s gross domestic product.
  • Create about 2.3 million jobs.

The more important gain may be less visible: technology, expertise, skilled employment and industrial ecosystems that remain after individual deposits decline.

That is why the real wealth in the transition minerals boom will not be measured only by what leaves African ports. It will also be measured by what no longer has to leave in raw form: refined lithium, battery precursors, processed graphite, copper products and other components that carry more value before export.

What Nigeria and Indonesia show about the model

Nigeria’s Dangote refinery is one of Africa’s clearest examples of large-scale beneficiation. Built in the Lekki Free Zone outside Lagos at a cost of about $20 billion, the 650,000-barrel-a-day facility is Africa’s largest single-train refinery.

Since it began production in early 2024, it has helped change Nigeria’s energy sector. For decades, Nigeria imported much of its refined fuel despite being a major oil producer, spending billions in foreign exchange. The refinery now supplies much of the domestic market and exports petrol, diesel and jet fuel to Ghana, Cameroon, Togo, Burkina Faso and Ivory Coast.

Between February and March 2026, Nigeria’s clean petroleum exports more than doubled from about 100,000 barrels a day to 214,000 barrels. The facility has also helped anchor related industries, including marine infrastructure, storage terminals, petrochemical plants and fertiliser production.

Indonesia offers another example. After banning exports of unprocessed nickel ore on January 1, 2020, it became a leading producer and exporter of processed nickel products. The country targeted $21.3 billion in foreign investment in mining and processing projects. Its nickel product exports rose from less than $1 billion in 2015 to nearly $20 billion in 2022.

That boom brought new smelters, refineries, battery-material plants and electric vehicle manufacturing. It also brought environmental and labour concerns, a reminder that industrial policy is not automatically clean or fair simply because it is domestic.

Why regional integration is not optional

No African country needs to make every battery cell or electric vehicle component on its own. The relevant minerals are spread across different economies: copper, cobalt, lithium, graphite and manganese do not all sit neatly inside one border, because geology declined to read the policy brief.

That makes regional integration practical, not decorative. If Zambia refines copper, Zimbabwe processes lithium, the Democratic Republic of the Congo produces battery precursors, and South Africa manufactures battery components, each economy can support the others.

Shared power systems, transport corridors, research institutions, technical standards and larger integrated markets will help determine whether Africa exports minerals or manufactures products. The African Continental Free Trade Area is central to that effort. If implemented properly, it could lower trade barriers, allow countries to specialise and turn scattered mineral deposits into regional manufacturing systems.

The energy transition gives Africa a chance to renegotiate its role in the global economy. The continent has supplied the raw material for other people’s industrial revolutions before. This time, the stronger position belongs to countries that insist on processing, skills, investment and technology at home before the next shipment leaves the port.
