MTM Critical Metals Unveils Game-Changing Gallium and Germanium Recovery Tech

A Breakthrough in Critical Metal Recovery

MTM Critical Metals Ltd (ASX: MTM) has announced a significant technological milestone in the recovery of gallium (Ga) and germanium (Ge) from semiconductor metal refining waste. Using its proprietary Flash Joule Heating (FJH) technology, MTM achieved recovery rates of approximately 90% for gallium and 80% for germanium, matching or exceeding traditional recovery methods. This breakthrough was accomplished at MTM’s Houston, Texas laboratory and represents a major step forward in sustainable, high-efficiency metal recovery.

Unlike conventional processes that rely heavily on acid leaching and solvent extraction, methods often plagued by environmental and cost inefficiencies, MTM’s FJH technology uses rapid, high-energy pulses to volatilise and recover metals without hazardous chemicals. This not only streamlines processing but also significantly reduces waste and emissions, positioning MTM at the forefront of environmentally responsible critical metal recycling.

Strategic Importance Amid Geopolitical Tensions

The timing of MTM’s breakthrough is particularly notable given the tightening of export restrictions on gallium and germanium by China, which dominates global supply chains. With China producing over 95% of the world’s gallium and around 70% of germanium, its recent export bans have heightened supply chain vulnerabilities for Western nations, especially the United States, which relies heavily on imports for these metals.

MTM’s technology offers a commercially viable, domestic alternative to secure these critical materials essential for semiconductors, defence systems, and renewable energy technologies. The company’s Managing Director and CEO, Michael Walshe, emphasised the strategic and economic opportunity this presents, highlighting the potential to reduce dependence on foreign-controlled supply chains and create a sustainable circular economy for these metals.

Partnerships and Market Potential

MTM’s collaboration with Indium Corporation, one of the largest Western suppliers of refined specialty metals, has been instrumental in sourcing high-value feedstock and accelerating the commercialisation pathway. Indium’s Business Unit Manager, Markus Roas, described MTM’s results as a potential industry game-changer, underscoring the importance of establishing circular supply chains for critical technology metals.

The market opportunity is substantial. Gallium and germanium prices have surged sharply amid supply disruptions, with gallium prices increasing over 50% in 2024 alone. MTM’s ability to recover these metals efficiently from semiconductor waste and scrap could unlock a multi-billion-dollar addressable market, especially as governments and industries seek resilient, onshore supply solutions.

Looking Ahead: Scaling and Diversification

MTM plans to expand its testing to include other critical metals such as indium and bismuth, which also face supply chain risks and rising demand. The company aims to optimise its FJH process further to improve metal purity and recovery yields, while exploring pilot-scale industrial applications.

With millions of tonnes of semiconductor waste currently landfilled globally, MTM’s technology could tap into a vast, underutilised resource base. This not only offers economic upside but also aligns with broader sustainability goals by reducing electronic waste and promoting metal recycling.

As MTM advances towards commercialisation, its progress will be closely watched by investors and industry stakeholders eager for innovative solutions to critical metal supply challenges.
