HARARE, Feb 25 (Reuters) - Zimbabwe has suspended exports of all raw minerals and lithium concentrates with immediate effect, its mines ministry said in a statement on Wednesday, after the government alleged malpractices and leakages.
Shares of Lithium rose on the news. Sigma Lithium up 28%; Albemarle up over 8%; Lithium Argentina up over 7%; SQM up over 4%.
The ministry said the ban on exports would remain in place until further notice and applied to all minerals currently in transit.
"Government expects cooperation of the mining industry on this measure which has been taken in the national interest," the statement said.
"Government remains committed to ... in-country value addition and beneficiation, compliance, and accountability in the exportation of Zimbabwe's mineral resources," it added.
In a letter seen by Reuters on Wednesday and addressed to Zimbabwe's Chamber of Mines, which represents major mining companies, the mines ministry said it would realign export processes due to concern about "continued malpractices during the exportation of minerals".
"This review is part of a broader effort to curb leakages and enhance efficiency within our systems," the ministry wrote on February 17.
Zimbabwe's ban on lithium concentrates was previously expected to come into effect in 2027 as part of a push for more local processing.
Africa's top producer of the battery mineral exported 1.128 million metric tons of lithium-bearing spodumene concentrate in the year ended December 2025, up 11% from the year before.
The southern African country has rapidly expanded spodumene output in recent years following significant investment by Chinese mining firms including Zhejiang Huayou Cobalt 603799.SS, Sinomine 002738.SZ, Chengxin Lithium Group 002240.SZ and Yahua 002497.SZ.
Most of the concentrate is exported to China for further processing into battery-grade materials, but Zimbabwe has been pressing the miners to process more of the minerals in the country as it seeks greater benefits from the global shift to cleaner sources of energy.
Huayou recently built a $400 million plant to further process lithium concentrates into lithium sulphate, an intermediate product which can be refined into a battery-grade material such as lithium hydroxide or lithium carbonate.
Sinomine has also announced plans to build a $500 million lithium sulphate plant at its Bikita mine in Zimbabwe.
