MTM Critical Metals Ltd recently announced a major breakthrough in critical mineral recovery, achieving high-grade antimony extraction from U.S.-sourced electronic waste using its proprietary Flash Joule Heating (FJH) technology.
The company reported a 98% metal conversion rate and recovered antimony at a concentration of 3.13%, significantly higher than typical global mine grades which range between 0.1% and 1.0%.
This development signals the commercial viability of MTM’s urban mining approach and aligns with the United States’ strategy to secure domestic sources of critical minerals.
Antimony is designated a critical mineral by both the U.S. Department of Defense and the Department of Energy due to its strategic applications in ammunition, semiconductors, and battery production.
The United States currently lacks domestic antimony mining and relies predominantly on imports, especially from China.
MTM’s success in recovering the metal from legacy e-waste streams supports the case for onshore recovery solutions and underpins its ongoing engagement with U.S. government stakeholders.
