The beneficiation bargain

The short version

The third quarter of 2026 settled a question that had been open for years: when African governments ban raw mineral exports, Chinese companies build the factories. Zimbabwe's lithium earnings nearly quadrupled, the DRC banned copper and cobalt concentrate exports, and Chinese plants moved from announcements to construction across the region.

The quarter also exposed the limits of that bargain. Processing capacity does not change who owns the mine, who finances the trade or who captures the margin. Western counter-financing grew — a €12 billion EU package for South Africa, a $20 billion Quad framework, a $491 million US compact for Zambia — but the projects China started were already further along.

The ban that worked

Zimbabwe was the test case. It banned raw lithium exports in 2024 and spent 2026 extending the policy. In July the government designated 13 more minerals — cobalt, platinum group metals and rare earths among them — for a raw-export ban from the start of 2027. In the same month, Mutapa Energy Resources confirmed $300 million from Zhejiang Huayou Cobalt and Tsingshan for the Sandawana lithium mine and its processing plant.

The numbers followed. First-half lithium exports reached $782 million, up 230% year on year. By the end of September, nine-month lithium sales were $2.16 billion, nearly four times the whole of 2025, driven by a 283% rise in spodumene prices. Lithium sulphate — the processed product — contributed $190 million, shipped from Huayou's Arcadia plant, the first of its kind in Africa.

Zimbabwe is now trying to move further up the chain. Officials travelled to China in September to visit the parent companies of Huayou, Sinomine, Chengxin and Sichuan Yahua, with engineers and commercial specialists in the delegation. The ambition is battery materials and solar panels, not just sulphate. Whether a country with 84% informal employment and a collapsed railway can build that chain is a different question; the railway to Maputo opened in July and the state operator moves about 2 million tonnes a year, down from 12 million in the 1990s. Sinomine's Bikita plant is due in mid-2027.

The DRC's harder test

The DRC went further. A joint ministerial order signed on 29 June and published in August banned copper and cobalt concentrate exports, replacing broad exemptions with one-year strategic waivers granted by the mines minister. The government cited Kamoa-Kakula's smelter — Africa's largest, commissioned in June — as proof that domestic processing is now possible.

The economics are less tidy. The DRC produced 3.2 million tonnes of copper in 2025 and holds 80 million tonnes of reserves, but its mining sector faces a power deficit of about 1 GW and a road and rail network that cannot move the output. The Manono lithium project began production in May. Mota-Engil won a 30-year concession for the Dilolo-Sakania railway, and the Africa Finance Corporation is raising $3-5 billion to expand the Lobito corridor. Without that infrastructure, a concentrate ban mostly shifts the bottleneck rather than removing it.

Chinese ownership is the other constraint. Chinese firms control roughly 80% of DRC cobalt output and hold stakes across the largest copper and cobalt mines. A ban that forces processing onshore therefore hands more of the value chain to the same companies that already own the mines.

China builds what Africa asks for

The quarter's clearest pattern was Chinese responsiveness. When Tanzania wanted a regional processing hub, Shenghe Resources began building a heavy-minerals separation plant at Pangani, designed to take feedstock from Mozambique, South Africa and Madagascar. When Zimbabwe wanted sulphate, Sinomine, Huayou and Sichuan Yahua built plants. When Namibia wanted value addition, eight agreements signed in Beijing in July committed to local processing of uranium, lithium and rare earths.

South Africa took a different route. In August a delegation led by Electricity Minister Kgosientsho Ramokgopa pitched R2.2 trillion — about $122 billion — of energy investment to Chinese firms under the country's 2025 integrated resource plan. By September, three Chinese manufacturers had confirmed transformer, wire and pylon plants in South Africa. The pitch was framed as industrial policy: local manufacturing in exchange for access to the grid build-out.

The aggregate numbers reflect the shift. Chinese BRI investment in Africa rose 254% in the first half of 2026 to $33.5 billion, with Africa taking 67% of global BRI activity. Much of it went to energy and metals rather than transport.

The corridor paradox

The Lobito Corridor was supposed to be the West's answer to Chinese logistics dominance: a 1,600km railway from the Copperbelt to Angola's Atlantic coast, financed by the US, EU and development banks. The quarter produced a series of uncomfortable findings about it.

ECDPM calculated that EU support amounts to about €112 million, not the headline billions, and that the $550 million US rail loan had not been disbursed. Between 80% and 95% of the copper moving on the line is China-bound. In September, CEDESA argued that China effectively controls a key segment through its influence over contractor Mota-Engil and its ownership of the mines feeding the line. Days earlier, a Chinese contractor, NERIN Engineering, won a $498 million contract to build a copper tailings plant at Chingola — the planned Zambian terminus of the US-backed corridor.

The lesson is not that Lobito is pointless. It is that building a railway does not change who owns the cargo. Western financing can shorten the route without changing the destination.

The West's cheque

Western commitments nevertheless grew. The EU's €12 billion South Africa package, agreed in June, ties investment to beneficiation. The Quad's $20 billion framework names Lobito, Nacala and TAZARA as platforms. The US expanded its $491 million Zambia compact, signed a critical minerals agreement with the DRC and backed Orion's purchase of Glencore stakes. In September, Team Europe launched R1 billion of green hydrogen and minerals projects in South Africa.

The gap is scale and speed. A CRS report in August found Africa supplied 99.9% of China's cobalt imports, 91% of its chromium and 86% of its natural graphite in 2025, and that Chinese FDI in African mining stood at $10.1 billion. CSIS told Congress that Africa's share of global exploration spending had fallen from 16% to about 10%, even as demand rose. Western money is arriving as offtake and guarantees; Chinese money arrives as plants.

What the quarter settled

Three things became clear between July and September. Export bans work in the narrow sense that they force processing investment, but they do not by themselves transfer ownership or margin. Chinese firms are the fastest suppliers of the processing capacity that African governments demand. And the Western alternative is still mostly a financing framework rather than a building programme.

The next test is whether the DRC's concentrate ban survives its own infrastructure gap, and whether Zimbabwe's sulphate plants are running before its 2027 ban on 13 more minerals takes effect. If they are, the beneficiation bargain will look durable. If they are not, the policy will have succeeded mainly in moving the smelter, not the value.
