Metallium Reports Successful Testing of its Proprietary Flash Joule Heating Technology on Rare Earth Elements, Germanium, PGMs and Red Mud/Gallium Advances Multiple Commercial Opportunities
Rhea-AI Summary
Metallium (ASX: MTM, OTCQX: MTMCF, MTMLY) reported successful testing of its proprietary Flash Joule Heating (FJH) technology across multiple critical metal feedstocks, including rare earth ores, germanium-bearing wastes, spent catalytic converters and red mud/gallium streams.
The company converted unbeneficiated rare earth ore with about 12% TREO into >83 wt% mixed REE chloride, with over 4x NdPr enrichment. Germanium was enriched up to 280x from zinc smelter waste, 240x from semiconductor waste and 35x from defense-related waste. Testing on catalytic converters produced a >60% purity PGM-rich product in a single unoptimized cycle, while red mud tests removed ~99% iron and 94% silicon, retained ~95% aluminum and concentrated gallium. All programs were initiated by industry participants, with commercial discussions underway.
Positive
- REE chloride product >83 wt% from ~12% TREO ore with >4x NdPr enrichment
- Germanium enrichment up to 280x (zinc waste), 240x (semiconductor), 35x (defense waste)
- PGM-rich product >60% purity from spent catalytic converters in a single unoptimized FJH cycle
- Red mud processing removed ~99% Fe, 94% Si, retained ~95% Al while concentrating gallium
- Industry-driven test programs with commercial discussions ongoing with defense, manufacturing and critical minerals participants
- First commercial FJH site operating in Texas via subsidiary Flash Metals USA
Negative
- None.

Mining of these critical metals and minerals will take years to get up to speed – they may be able to be secured right now in already existing feedstocks through FJH.
"While the processing of electronic waste (e-Waste) remains our immediate commercial priority, this broader testing program continues to demonstrate the potential application of our FJH platform across a substantially wide range of critical metal and industrial feedstocks, which open significant additional markets for commercialization of the technology," said Michael Walshe, management director and CEO of Metallium.
He added that Metallium continues to work separately with Indium Corporation and other major semiconductor industry suppliers to progress strategic sourcing initiatives for gallium, germanium, indium and other technology metal-bearing secondary raw materials for future processing. "These initiatives are complementary to the additional commercial opportunities arising from the testing programs conducted here," he added.

The successful testing results included:
- Successfully converting raw, unbeneficiated REE ore containing approximately
12% TREO directly into a more than 83 wt% mixed REE chloride product, achieving more than 4x enrichment of NdPr in an initial unoptimized test. - Successfully enriching germanium by up to 280x from zinc smelter waste, 240x from semiconductor manufacturing waste and 35x from defense-related industrial waste, demonstrating applicability across multiple strategic secondary feedstock
- Successfully produced a more than
60% purity PGM-rich product containing platinum, palladium and rhodium from spent automotive catalytic converters in a single, unoptimized treatment cycle, demonstrating potential for a materially simplified recycling pathway vs. conventional processing. - In the area of red mud/gallium, testing removed approximately
99% of iron and94% of silicon while retaining approximately95% of aluminum, with gallium concentrated into a separate product stream, demonstrating the potential to recover critical metals while upgrading a major industrial waste stream.
All of the testing was initiated at the request of industry participants across defense, manufacturing and critical minerals, with commercial discussions ongoing between these participants and the company regarding potential agreements.
Metallium (https://www.metalliuminc.com) is pioneering a low-carbon, high-efficiency approach to recovering critical and precious metals from mineral concentrates and high-grade waste streams. The company's patented Flash Joule Heating (FJH) technology enables the extraction of high-value materials, including gallium, germanium, antimony, rare earth elements, and gold – from feedstocks such as refinery scrap, e-waste and monazite. The company has its first commercial site in
