Using its in-house Flash Joule Heating (FJH) technology, MTM Critical Metals Ltd. said that it has successfully recovered high-grade antimony (Sb) from electronic trash originating in the United States. With a 98% conversion rate, 3.13% antimony was produced, which is more than the usual concentration found in antimony mining grades across the world (0.1–1.0%).
This innovation shows how onshore, urban mining solutions that support the US critical minerals agenda may be profitable. Both the U.S. Department of Defense and the Department of Energy have classified antimony as a key mineral. It is essential to sectors including battery manufacture, semiconductors, and explosives. Due to its present lack of local antimony production, the United States is mostly dependent on imports from China.
MTM’s findings complement the company’s continuing conversations with U.S. government stakeholders about possible financing support and demonstrate the strategic importance of recovering essential metals from legacy e-waste streams.
Michael Walshe, Managing Director & CEO of MTM, commented, “Achieving 98% recovery from e-waste at over 3% grade shows the transformative power of our technology. We’re well positioned to contribute to U.S. supply chain resilience and advance toward commercial deployment.”
MTM is still working with U.S. regulators on expanding operations, and has just obtained a pre-permitted demonstration site in Texas.
With offices in Houston, Texas, and Perth, Western Australia, MTM Critical Metals is an expert in cutting-edge metal recovery methods. Flash Metals USA, the company’s fully owned US affiliate, is the exclusive licensee of the novel Flash Joule Heating technology, a metal recovery and mineral processing technique created by Rice University researchers. Additionally, MTM has exploration properties in Western Australia and Quebec that have the potential to yield gold, rare earth elements (REE), and niobium (Nb).
