MTM Critical Metals (ASX:MTM) unveiled new results from its Flash Joule Heating (FJH) prototype testing, marking a significant leap in the recovery of Rare Earth Elements (REE) and critical metals from coal fly ash (CFA) samples. The findings indicate a potential revolution in metal recovery technology with implications for various industries.
The FJH prototype testing conducted by MTM exhibited a remarkable increase in the recovery of REEs and Critical Metals from CFA samples. The ASX release underscores several significant points, including:
- Noteworthy Recovery Rates: The FJH prototype yielded a substantial +50% increase in the recovery of REEs and Critical Metals, compared to traditional acid leach methods.
- Successful Scale-Up: Initial testing at a 50x scale-up from Rice University's proof of concept demonstrated the efficacy of the FJH technology.
- Promising Prospects: MTM plans to conduct further FJH testing on various waste sources of REE and Critical Metals, such as Bauxite Residue, E-Waste, and end-of-life Lithium-Ion Batteries.
Implications and Future Prospects
The implications of these findings extend beyond the realm of metal recovery. Flash Joule Heating technology not only promises higher recovery rates but also presents opportunities for cost savings and waste reduction in the leaching process. With ongoing testing and refinement, MTM aims to advance the design of a larger Pilot FJH Plant, paving the way for commercial-scale opportunities.
Flash Joule Heating: An Overview
FJH technology, developed in collaboration with Rice University, represents a significant advancement in processing and recycling methods. By employing rapid and intense heating, FJH facilitates the direct recovery of critical metals while rendering materials more amenable to conventional acid leaching methods. This electro-chemical process holds promise for extracting a range of valuable metals from various waste materials, including coal fly ash and lithium-ion batteries.
The results from MTM's Flash Joule Heating prototype testing signify a major breakthrough in metal recovery technology. With the potential to revolutionise current industry practices, FJH offers a sustainable solution for harnessing critical metals from waste materials. As MTM continues to push the boundaries of innovation in metal recovery, the implications for various sectors, including mining, renewable energy, and electronics, are profound.
