Summary of Key Points
Recently, Zimbabwe issued a strict order with no grace period: the export of antimony and tungsten—two essential metals for new energy and high-end manufacturing—is completely prohibited, even for the raw minerals that have already been mined and piled up at ports, ready for shipment. This follows the ban on lithium mineral exports earlier this year. By “locking in the raw minerals” and forcing foreign investment to build processing plants locally, Zimbabwe has reaped tangible benefits: the revenue from mining has more than doubled despite less mineral extraction. In the past year, nearly 10 African countries have followed Indonesia’s example of using mineral bans to boost their economies. No longer content with merely selling cheap minerals for low wages, these countries have taken advantage of China’s zero-tariff policy for all goods from the 53 African countries with which it maintains diplomatic relations. The traditional model of “Africa mining, China processing” is being transformed into a new one where “China provides technology and builds factories, Africa processes locally, and high-value products enter China duty-free.” This change is fundamentally altering the rules of the global new energy industry.

Simplified Explanation
1. Zimbabwe’s Mineral Bans Are Not Impulsive: They Are Profit-Making Strategies
Many think Zimbabwe’s mineral bans are arbitrary decisions, but the calculations are clear. Previously, selling lithium concentrate meant simply screening the mined ore and shipping it, with only a small profit per ton. Now, by preventing the export of raw minerals, Zimbabwe forces foreign investors to build smelters locally to process the ore into high-value lithium sulfate, significantly increasing the price per ton. Public data shows that Zimbabwe’s lithium exports increased slightly in the first quarter of 2026, with revenue soaring from $84.19 million to $179 million—more than a doubling. Although China’s import of antimony and tungsten from Zimbabwe is minimal, these metals are among the last few that Zimbabwe controls. After already regulating lithium and cobalt, the ban on these metals ensures that all profits from the processing are retained domestically. This strategy recognizes that selling raw materials is less profitable than selling finished products.
2. A Global Trend of Mineral Bans: Africa Doesn’t Want to Be Just Miners
For decades, Africa has held 30% of the world’s key mineral reserves, with the Democratic Republic of Congo accounting for 75% of global cobalt production and Zimbabwe’s lithium mines being of high quality and low cost. However, Africa has often lost money on these resources, selling them for a few thousand dollars per ton while the value added through manufacturing (e.g., in electric vehicles) went to other countries. Indonesia was the first to realize this and banned nickel exports, forcing nickel companies to set up smelters there, resulting in a several-fold increase in nickel revenue and transforming it into a key player in the new energy industry. Now, many African countries are following suit, aiming to move away from being mere miners. With the global explosion in new energy and AI, these previously overlooked metals have become highly valuable. Over the past year, more than 10 African countries have introduced mineral bans and required foreign investment in local processing plants. The African Union’s “African Mining Vision 2030” aims to change this situation.
3. Mineral Bans Are Profitable, but There Are Challenges
While banning exports is easy for governments, setting up local processing plants is much more difficult. Africa faces two major hurdles: technical expertise and power supply. For tungsten, for example, the ore must be processed into concentrate and then through several complex chemical steps to produce high-value products. Zimbabwe lacks the necessary technology and skilled workers. Additionally, power supply is a critical issue; smelters require constant power, but the country cannot even ensure stable electricity supply for households, resulting in significant annual losses. Without overcoming these challenges, mineral bans will only lead to wasted resources without additional profits.
4. New Cooperation between China and Africa
The traditional model of Chinese investment in African mining, followed by domestic processing, is being replaced by a new one. China is providing technology, equipment, and microgrids to help Africa process minerals locally into high-value products. With zero tariffs for products from these 53 African countries, these products can enter China duty-free, integrating into China’s large new energy and manufacturing supply chains. This benefits both sides: Africa earns processing fees and develops its industries, while China obtains stable supplies of raw materials without being constrained by international prices.
5. Changes Benefit Ordinary People
Some might worry about rising prices for lithium and antimony, but the opposite is true. In the past, global mineral prices were volatile due to speculation, with consumers bearing the costs. Now, with direct cooperation between China and Africa, prices are more stable. This new model reduces costs for consumers, making electric vehicles and solar power more affordable. It also promotes economic development in Africa and strengthens China’s global supply chain, reducing its reliance on European and American markets.

In summary, Zimbabwe’s mineral bans are part of a broader trend where African countries are seeking to control their resources and develop their own industries, while China is expanding its new energy and manufacturing capabilities. These changes are likely to benefit ordinary people by reducing costs and improving access to essential goods and services.
