Africa’s first lithium sulphate plant rises in Zimbabwe

Construction of Africa’s first lithium sulphate processing plant at Prospect Lithium Zimbabwe’s Arcadia mine outside Harare, part of the country’s push to add value to its critical minerals

ON the eastern edge of Harare, cranes, reactors and miles of industrial piping are slowly sketching the outline of a new kind of mining future — one where Zimbabwe sells chemistry, not just rock.

Prospect Lithium Zimbabwe is constructing Africa’s first lithium sulphate processing plant at its Arcadia operation, a landmark investment that moves the country away from exporting raw concentrate and towards producing higher-value battery intermediates for the global electric-vehicle market while supporting Harare’s broader industrialisation drive.

From ore to advanced chemicals

For decades, Zimbabwe’s lithium story followed a familiar pattern: mine spodumene, load it onto trucks, ship it abroad, and watch overseas refiners capture most of the value. Arcadia is now breaking that mould.

Prospect Lithium is investing around $400 million in a purpose-built lithium sulphate facility adjacent to the mine, with commissioning expected in 2026. Instead of exporting raw concentrate, the plant will convert locally mined ore into lithium sulphate — a critical intermediate used to manufacture battery-grade lithium chemicals for electric vehicles, grid storage and consumer electronics.

The site looks less like a traditional mine and more like a modern chemical complex. Processing units, filtration systems and storage tanks dominate the landscape, signalling a step change from extraction to manufacturing.

Company executives say the logic is simple: move up the value chain. By exporting a processed product rather than raw material, Zimbabwe can command stronger margins and secure a deeper foothold in the clean-energy economy.

A real test of beneficiation policy

The plant arrives at a pivotal policy moment. Harare has made mineral beneficiation a core pillar of its economic agenda and has signalled plans to ban exports of unprocessed lithium concentrate from 2027.

Prospect Lithium’s investment gives that policy credibility. Rather than threatening production, the facility provides a practical route for miners to comply with new rules while remaining commercially viable.

Officials privately view Arcadia as a pilot project — proof that Zimbabwe can host sophisticated mineral processing instead of remaining a supplier of raw materials to foreign industries.

Yet success will depend on reliable power, water and transport infrastructure. If the plant runs smoothly, it could become a national benchmark; if not, critics will argue that ambition outpaced capacity.

Jobs, skills and local impact

Beyond export revenues, Prospect Lithium has framed the project as a catalyst for industrial development around Harare.

Hundreds of workers have already been employed during construction. Once operational, the plant is expected to require chemists, engineers, technicians and logistics specialists — a new kind of workforce for Zimbabwe’s mining sector.

Local suppliers in transport, maintenance and industrial services are positioning themselves to support the facility. Training programmes and apprenticeships linked to Arcadia aim to ensure nearby communities benefit from skills transfer rather than merely hosting heavy industry.

Economists caution that these spillovers will determine whether Zimbabwe’s lithium boom translates into lasting development or fades as another commodity cycle.

Zimbabwe in the global battery race

Global demand for lithium continues to surge as carmakers accelerate the shift to electric vehicles and governments prioritise renewable energy storage. China still dominates processing, but supply chains are gradually diversifying.

By hosting Africa’s first lithium sulphate plant, Prospect Lithium is placing Zimbabwe closer to the centre of that market — not as a quarry, but as a processor.

Regional analysts say Arcadia could inspire similar downstream investments across southern and West Africa, where governments are increasingly wary of exporting raw critical minerals.

If successful, the project could mark a turning point: the moment Zimbabwe moved from selling rocks to producing the chemistry that powers the energy transition.
