MTM Critical Metals Recovers High-Grade Antimony at 98% from U.S. E-Waste

THE BOURSE WHISPERER: MTM Critical Metals ASX: MTM) has achieved a major breakthrough with the company’s Flash Joule Heating (FJH) process that recovers critical metals from electronic (e) waste.

MTM Critical Metals has achieved 98 per cent recovery of antimony from U.S. electronic waste, extracting 3.13 per cent antimony from printed circuit board feedstock using its proprietary FJH technology.

The company claimed the achieved grade far exceeds that of typical mined ore, noting that the largest primary deposits, such as China’s Xikuangshan, average just 0.5–0.7 per cent antimony.

The tested feedstock came from urban waste material from which MTM had previously reported ultra-high-grade gold, silver, and copper recoveries.

MTM has already secured over 1,100 tonnes per year of e-waste feedstock under long-term agreements with U.S. suppliers, separate from the material tested for the recent recovery work.

The company believes this provides a strong foundation for commercial deployment.

“This result demonstrates the strong technical and commercial potential of our FJH process for recovering strategic metals from e-waste,” MTM managing director & CEO Michael Walshe said in the company’s ASX announcement.

“Achieving 98% recovery of antimony at over 3% grade, from domestic urban feedstock, is particularly significant given the U.S. currently has no meaningful domestic antimony production.

“With antimony designated as a critical metal by both the DoD and DoE, these outcomes reinforce MTM’s ability to contribute to onshore supply solutions for high-priority metals.

“Combined with our recently secured, pre permitted demonstration site in Texas, we are well positioned to scale operations and advance commercial deployment.

“In parallel, the company is engaging with U.S. government agencies, including the DoD and DoE, regarding potential funding to support domestic critical metal recovery.

“While early-stage and non-binding, these discussions reflect strong interest in scalable U.S.-based refining technologies.

“The strategic role of antimony in defence, particularly in armour piercing alloys and flame-retardant systems, was a consistent theme during recent meetings in Washington.”
