Zimbabwe’s planned January 2027 ban on exports of unprocessed lithium concentrate is approaching while domestic conversion capacity remains insufficient to handle production from the country’s expanding lithium sector.
The only operating lithium-sulphate facility is controlled by Prospect Lithium Zimbabwe, a subsidiary of China’s Zhejiang Huayou Cobalt. Its concentrator produces about 400,000 tonnes of concentrate a year, while the company has said its sulphate plant is fully committed to its own feedstock and cannot process material from other producers.
New conversion plants face the 2027 deadline
Despite requests from producers for a delay, the Zimbabwean government has maintained the export prohibition and is requiring miners to process lithium domestically. Additional capacity is being developed by Sinomine Resource Group’s Bikita Minerals and Yahua Group’s Kamativi Mining Company. Both companies are building conversion facilities, but neither is expected to have its plant operating by January 2027.
This leaves a potential mismatch between lithium concentrate output and legally available domestic processing capacity when the export restriction takes effect.
Chinese investment has expanded lithium production
Chinese companies have invested approximately US$2 billion in Zimbabwean lithium mining and processing since 2021, supporting a rapid expansion of the country’s lithium output. Most of the resulting processing infrastructure, however, remains integrated with individual mining operations rather than available as merchant capacity for third-party producers.
Smaller miners could consequently face the need to stockpile concentrate, reduce production or arrange processing through larger Chinese-controlled operations once exports of unprocessed material are prohibited.
Processing access becomes a strategic issue
Companies that bring sulphate plants into operation first could gain greater negotiating leverage over third-party feedstock, potentially through higher treatment charges or commercial interests in smaller mining operations. The policy requires the development of mining, conversion, reagent supply, electricity and logistics capacity on compatible timelines. Zimbabwe has expanded lithium production and established a firm domestic-processing deadline, but independently accessible conversion capacity remains insufficient to accommodate the sector’s output.
