• Lithium generated US$746 million in H1 2026, led overwhelmingly by spodumene concentrates
• Chinese investors control more than 80% of Zimbabwe’s lithium production
• Processing expansion is increasing domestic value capture and deepening concentration across the value chain

Harare- Zimbabwe’s lithium industry generated US$746 million during the first half of 2026, establishing the mineral as one of the country’s fastest growing sources of mining revenue. Spodumene concentrates generated US$672.8 million, accounting for 90.2% of lithium earnings, and lithium sulphate contributed US$73.2 million, equivalent to 9.8%. Zimbabwe has entered commercial lithium chemical production, and most of the sector’s revenue still comes from material whose next processing margin is earned further along the battery supply chain.

Spodumene generated 9.2 times more revenue than lithium sulphate during the period largely because Zimbabwe continues to export much greater volumes of concentrate than its chemical plants can process. The economics change once the comparison moves to value per tonne. Lithium sulphate has undergone chemical conversion, purification and quality control before export, adding industrial processes that increase the value embedded in each tonne.

Lithium sales during the first quarter illustrate the potential. Volumes increased by only 2% to 240,826 tonnes and the value of those sales rose 106% to US$178.64 million. International lithium prices were recovering and Zimbabwe had also begun selling processed lithium products. Published aggregate data do not allow the entire value increase to be assigned to chemical processing, though the widening product mix establishes an additional channel through which earnings can increase without requiring equivalent growth in mined tonnage.

The most advanced example sits at Arcadia in Goromonzi. Zhejiang Huayou Cobalt invested approximately US$400 million in a lithium sulphate facility with installed capacity of about 50,000 tonnes annually. The plant was operating at roughly 60% of capacity by July after exporting Africa’s first commercially produced lithium sulphate from Zimbabwe in April.

The operation converts spodumene concentrate through hydrometallurgical treatment and purification into lithium sulphate. That additional chemistry requires power, reagents, specialised engineering, water treatment and laboratory capability. It also moves more processing activity, employment and operating expenditure into Zimbabwe before the mineral enters the downstream battery materials industry.

Arcadia is preparing to move further along that chain. Prospect Lithium Zimbabwe has been installing additional equipment aimed at crude lithium carbonate production, with management targeting production by the end of 2026 and an eventual product mix divided between sulphate and carbonate. Lithium carbonate would broaden Zimbabwe’s chemical export portfolio and create a route closer to the products used by cathode manufacturers.

The processing build out extends beyond Arcadia. Sinomine is developing major lithium sulphate capacity at Bikita, and Kamativi is also developing a sulphate project. Industry plans envisage annual lithium sulphate production reaching approximately 344,000 tonnes by 2030. Chinese companies have invested around US$2 billion in Zimbabwe’s lithium sector since 2021, placing the same investor group that developed much of the mining capacity at the centre of the transition into chemicals.

That ownership pattern defines the next stage of Zimbabwe’s lithium dependency. Chinese investors control more than 80% of production. Huayou controls Arcadia, Sinomine owns Bikita, Chengxin operates Sabi Star and Yahua participates at Kamativi. Their exposure extends into project finance, mine equipment, technical management, processing infrastructure and downstream market access.

The economic contribution from those investments is substantial. Arcadia alone has generated thousands of direct and indirect jobs. Domestic processing creates additional electricity demand, engineering activity, laboratory work, chemical procurement and taxable business activity. Royalties and corporate taxes remain in Zimbabwe, and the sulphate plant adds economic activity that concentrate exports cannot generate on their own.

The concentration risk now extends beyond mine ownership. The technology used to transform spodumene into lithium chemicals, the process expertise governing recoveries and purity, and many of the downstream customer relationships remain embedded within the global networks of the Chinese companies that own the plants. Zimbabwe is consequently capturing a larger portion of the processing chain inside its borders without achieving equivalent diversification in who controls the commercial infrastructure around that chain.

Government demonstrated its own leverage in February when it suspended exports of raw minerals and lithium concentrates. Zimbabwe had exported about 1.13 million tonnes of spodumene concentrate to China in 2025, representing roughly 15% of Chinese imports. The policy action reached a market that had become materially dependent on Zimbabwean supply. China’s Embassy subsequently advised companies to strengthen their assessment of policy and operating risks in Zimbabwe.

Government adjusted the framework in April by allowing concentrate exports to resume under quotas and requiring mining companies to commit to lithium sulphate plants ahead of the January 2027 prohibition on concentrate exports. The arrangement restored export revenue during the construction period and maintained pressure for investment further along the value chain.

The investment response since then has strengthened Government’s hand. Chinese companies continued building processing plants after the February suspension and March diplomatic warning. Huayou started sulphate exports, Sinomine advanced its Bikita processing project and other producers continued developing beneficiation plans. Zimbabwe’s resource base and its contribution to Chinese supply remain sufficiently important to sustain investor interest under a more demanding processing regime.

The harder question now concerns the mines whose own chemical plants will not be ready when concentrate exports close.

Zimbabwe currently has only one operating lithium sulphate plant, at Arcadia. That facility cannot take concentrate produced by other mines because its available processing capacity is already required for Arcadia’s own material. In practical terms, an independent lithium miner cannot currently send its concentrate to Arcadia, pay a processing fee and receive lithium sulphate for export.

That point exposes a weakness hidden by national processing capacity figures. A country can have a large lithium sulphate plant and still have no shared processing market. Arcadia’s capacity belongs to the Arcadia production system. Capacity available to another miner requires spare plant space, a commercial processing agreement and technical compatibility between the outside concentrate and the plant.

As at 27 August 2026, no operating Zimbabwean lithium sulphate facility has publicly confirmed spare processing capacity available to outside producers. Several plants are under construction, and the industry has already asked Government for more time because some facilities may miss the January deadline. The current problem therefore concerns access as much as total installed capacity.

That distinction is particularly important for smaller producers. A large mine can finance its own sulphate facility and dedicate the plant to its own feed. A junior mine may have an economic deposit without producing enough concentrate to justify several hundred million dollars of standalone chemical infrastructure. Closing concentrate exports without creating a processing route for those miners could leave commercially viable ore without a legal route to export markets.

The policy test can therefore be stated in measurable terms. By 1 January 2027, Government should be able to identify how many tonnes of concentrate produced by a mine without its own sulphate plant can actually be processed inside Zimbabwe. The publicly confirmed figure today is effectively zero because the only operating plant cannot accept outside material.

That finding changes the case for shared processing. Zimbabwe needs some large plants to operate as commercial processors for multiple mines, with producers paying a fee to convert concentrate into sulphate. Such arrangements already exist across other mineral industries through toll smelting and toll refining. They allow several mines to use one capital intensive processing facility without each company building an identical plant.

Government can accelerate that market by making access conditions part of the incentives granted to selected new plants. A processor receiving tax concessions, infrastructure support or preferential export treatment could reserve a defined portion of capacity for qualifying Zimbabwean producers. Treatment charges would remain commercial, and published access rules would prevent processing capacity from becoming another concentrated bottleneck.

The same principle applies to infrastructure. At least six additional beneficiation projects are under development. Building each as a completely independent industrial complex duplicates power installations, water systems, effluent treatment, chemical storage, laboratories and logistics infrastructure.

A shared lithium processing zone would reduce those fixed costs. Goromonzi already has an emerging cluster around Arcadia, and the Midlands carries another concentration of mineral production and infrastructure. A dedicated processing zone could provide common power, water treatment, chemical logistics, environmental systems and quality certification while individual companies retain their own production lines.

International experience provides a useful policy direction. Chile uses its lithium agreements to secure material for companies that undertake value added manufacturing inside the country. CORFO provides qualifying domestic processors with access to lithium carbonate from major producers under preferential long term supply arrangements, linking access to the mineral with investment in higher value products and local industrial capability.

Zimbabwe can apply the same economic principle to its hard rock industry. Mining and processing licences can require progressively higher domestic conversion according to a published timetable, and selected processors can be required to provide feedstock or processing access to downstream businesses that establish manufacturing locally.

Skills transfer should sit beside processing obligations. Every major chemical facility should contribute to structured training in hydrometallurgy, plant engineering, laboratory testing and battery precursor quality control. Zimbabwe needs enough local technical capability to operate, maintain and eventually design parts of the processing chain without permanent dependence on foreign technical teams.

The same requirement applies to market access. Chinese investment remains central to the industry because China dominates global lithium chemical conversion and battery manufacturing. A resilient Zimbabwean lithium sector also needs additional buyers, financiers and processing partners from Europe, Japan, South Korea and other battery markets.

Diversification carries an economic benefit before it becomes a diplomatic objective. Several buyers competing for Zimbabwean lithium improve price discovery. Several project financiers reduce the consequences when one capital market tightens. Multiple processing technology partners increase Zimbabwe’s negotiating power over plant construction, technical transfer and operating terms.

The H1 revenue split provides Government with a clear benchmark for measuring progress. Spodumene accounted for 90.2% of the US$746 million earned from the two reported lithium categories and sulphate contributed 9.8%. Beneficiation should progressively increase the chemical share of that revenue over the next several years.

The measurement should go further. Government needs to publish sulphate and carbonate production, plant utilisation, realised export value per tonne, local technical employment, domestic procurement and the amount of processing capacity available to companies that do not own chemical plants. Those metrics would distinguish genuine industry development from an accumulation of vertically integrated corporate facilities.

Arcadia’s 50,000 tonne sulphate facility reaching full utilisation is one measurable target. Commercial carbonate production provides another. Commissioning the plants now under construction adds capacity. The first verified processing agreement through which an independent miner sends concentrate to another company’s sulphate plant will mark an equally important milestone because it would establish the beginnings of a domestic processing market.

Zimbabwe has already moved further along the lithium value chain than most African producers. US$73.2 million in lithium sulphate earnings during the first half of 2026 places a monetary value on that progress. The US$672.8 million still earned from spodumene places an equally clear value on the work remaining.

The next phase carries a more difficult objective than simply building processing plants. Zimbabwe needs processing capacity that can serve an industry, technical knowledge that increasingly resides locally and enough financing and customers to prevent one commercial ecosystem from controlling every stage from the mine to the battery materials market.

Zimbabwe’s lithium dependency is moving up the value chain with beneficiation itself. The country has begun retaining more value before export. The strategic return will be determined by how much of the processing capability, technical knowledge and market access Zimbabwe can control once the plants are operating.
