In a move that's sent ripples through the tech and defence sectors, China has announced an immediate ban on exporting critical minerals—gallium, germanium, and antimony—to the United States. These elements are indispensable in manufacturing semiconductors, batteries, and military equipment. China's dominance in their production—accounting for 98% of the world's gallium and 60% of germanium—means this decision could significantly disrupt global supply chains.

Enter MTM Critical Metals Limited (ASX: MTM), an Australian company poised to turn this geopolitical challenge into an opportunity. MTM has exclusive rights to develop Flash Joule Heating (FJH) technology for critical mineral processing and recycling outside the laboratory of Dr James Tour, a globally recognised materials scientist based at Rice University in Texas. The technology, developed under Dr Tour’s direction, uses a high-voltage current to rapidly heat and process materials, enabling efficient extraction of valuable metals from complex or low-grade sources, including industrial waste and scrap.
The FJH process stands out because of its speed, energy efficiency, and ability to handle challenging materials that traditional methods struggle with. Unlike conventional mineral extraction processes that can be costly and environmentally damaging, FJH promises a lower carbon footprint and the ability to tap previously uneconomical sources.
While the technology is still at the pilot stage, it has already delivered promising results in lab trials, demonstrating the ability to recover high-value metals like gallium, germanium, and rare earths. MTM’s partnership with Indium Corporation is expected to accelerate the commercialisation of the technology, with testing already underway on real-world feedstocks provided by Indium.
Michael Walshe, MTM's Chief Executive Officer, highlighted the advanced state of the technology: “Flash Joule Heating is not just a concept. It's a tested, scalable solution that could redefine critical mineral processing and recovery. Our collaboration with Indium is the first step in bringing this revolutionary approach to the market.”
The timing of this collaboration is particularly fortuitous. With China's export ban causing concerns over supply shortages and potential price increases, MTM's initiative could provide a timely alternative. By focusing on recycling and processing scrap materials, MTM and Indium Corporation aim to mitigate the impact of supply disruptions and contribute to a more secure and sustainable supply chain for critical minerals.
In summary, MTM's exclusive rights to Dr Tour’s Flash Joule Heating technology, combined with its strategic partnership with Indium Corporation, position the company as a frontrunner in addressing supply chain vulnerabilities. As the world grapples with the implications of China's export ban, MTM’s cutting-edge technology and strategic vision could play a crucial role in ensuring the availability of essential materials for critical industries.
