Chinese mining companies are accelerating investment in lithium refining capacity in Zimbabwe as the government tightens export rules on raw ore in a bid to capture more value from the fast-growing battery minerals sector.
The developments come as seeks to transform its role in the global lithium supply chain, moving away from exporting unprocessed spodumene concentrate toward higher-value lithium sulfate production.
Zimbabwe, Africa’s largest lithium producer, has traditionally exported most of its output in raw or semi-processed form, limiting its earnings from a mineral that is increasingly central to electric vehicle and renewable energy technologies.
But that model is now shifting, driven by both policy changes and new capital inflows from Chinese firms expanding downstream processing operations in the country.
China’s has announced plans to raise up to 5.2 billion yuan (US$764 million) to fund several projects, including a lithium refinery in Zimbabwe, marking a significant expansion of its footprint in the country’s mining sector.

The company said the funding would support development work at its Bikita mine, where it is building a refinery with capacity to produce about 100,000 tonnes of lithium sulfate annually.
Lithium sulfate is a higher-value intermediate chemical used in battery manufacturing, and typically commands a significantly higher price than spodumene concentrate, the form in which much of Zimbabwe’s lithium is currently exported.
Another Chinese firm,, has already completed what authorities described as Africa’s first exports of lithium sulfate, following the commissioning of a 50,000-tonne-per-year refinery at its Arcadia mine.

A third player,, has also begun construction of a lithium sulfate processing facility at the Kamativi mine, further reinforcing the shift toward domestic value addition.
Zimbabwe’s government has been tightening regulations to push miners toward local processing.
In February, authorities imposed a ban on exports of lithium concentrates before replacing it in April with a quota system designed to ease the transition while firms adjust their operations.
A full ban on concentrate exports is scheduled to take effect in January 2027, signalling a firm policy direction toward domestic beneficiation.
Officials argue that exporting raw lithium undermines the country’s potential earnings and limits industrial development, especially at a time when global demand for battery materials is rising rapidly.
The economic gap between raw and processed lithium highlights the incentive for change.

Recent market data showed lithium sulfate delivered to China from Africa trading at about $8,751 per tonne, compared with $2,595 per tonne for spodumene concentrate, underscoring the potential revenue gains from refining.
The government says domestic processing could help Zimbabwe capture more value, reduce reliance on volatile commodity exports and build a stronger industrial base.
For Chinese companies, the shift aligns with broader efforts to secure long-term supply chains for critical minerals needed in electric vehicle batteries and energy storage systems.
Firms such as Sinomine argue that local refining also reduces transport costs and improves margins, particularly when global lithium prices fluctuate.
However, analysts caution that Zimbabwe’s strategy carries execution risks, including financing constraints, infrastructure limitations and the ability of smaller mining operators to comply with new rules.
The success of the policy will depend on whether planned refineries are completed on schedule and whether additional investment follows across the sector.
Zimbabwe earned about $571 million from lithium exports in 2025, according to official figures, but authorities believe that figure could rise significantly if more value is captured domestically.
If successful, the policy shift could reposition the country as a more integrated player in the global battery supply chain, moving beyond raw mineral exports toward higher-value industrial production.
