MTM Critical Metals reports high-grade antimony recovery from US e-waste

MTM Critical Metals (ASX: MTM; OTCQB: MTMCF) announced Tuesday it has achieved 98% recovery of antimony from US electronic waste, extracting 3.13% Sb from printed circuit board feedstock.  The Australian company, whose US, Houston-based subsidiary Flash Metals USA, is commercializing its proprietary Flash Joule Heating (FJH) technology to recover critical metals and gold from E-waste.  Last month, MTM secured a pre-permitted site in the US Golf Coast petrochemical corridor in Chambers County, Texas, as its first facility. The tested feedstock — the same urban waste material from which MTM previously reported ultra-high-grade gold, silver, and copper recoveries — highlights the untapped value of complex e-waste streams, MTM said. The tested material — sourced from U.S.-origin printed circuit boards — had undergone upstream thermal processing to remove plastics and volatiles, yielding a concentrated, metal-rich carbonaceous residue.  This “urban ore” contained 3.13% antimony, a grade more than three times higher than some of the world’s largest primary deposits, including China’s Xikuangshan, and significantly above the global mined ore range of 0.1–1.0% Sb, MTM said.  These results, the company said, directly support US efforts to re-establish domestic refining capacity.  MTM said it has already secured over 1,100 tonnes per year of e-waste feedstock under long-term agreements with U.S. suppliers, which provide 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 CEO Michael Walshe said in a news release.  “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 Sb production,” Walshe said. “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.”  Walshe also said the company is engaging with US government agencies, including the DoD and DoE, regarding potential funding to support domestic critical metal recovery. Weiter zum vollständigen Artikel bei Mining.com Weiter zum vollständigen Artikel bei Mining.com
