Metallium Continues to Advance Production Capabilities of Multi-Unit FJH Chlorination

Three reactors moved from inert commissioning into reactive processing with chlorine and platinum-group-metal-bearing feedstock.

Rhea-AI Summary

Metallium (MTLMY, MTMCF) completed a 12-hour multi-unit Flash Joule Heating campaign using catalytic converter feedstock containing platinum-group metals.

The third-quarter 2026 campaign at its Texas Technology Campus used three reactors operating with chlorine, moving from earlier inert commissioning into reactive processing. The campaign was designed to generate operating and metal-processing data on feedstock behavior and interactions between process variables under chlorination conditions. Metallium expects to produce saleable metal-bearing products, including metal chlorides and intermediate forms, before a full-scale commercial launch next year.

chlorination technical

"reactive processing under high-temperature reactive chlorination conditions"

Chlorination is the controlled introduction of chlorine or chlorine-containing compounds into water or wastewater to kill or inactivate disease-causing microorganisms and prevent microbial regrowth. It works by oxidizing cell walls and disrupting microbial metabolism, and is applied as gaseous chlorine, sodium hypochlorite (liquid bleach), or calcium hypochlorite (solid); utilities monitor chlorine residuals to ensure continued disinfection. A notable limitation is formation of disinfection byproducts (such as trihalomethanes and haloacetic acids), which are regulated and can require treatment adjustments or alternative disinfectants.

thermochemical technical

"thermochemical behavior of the feedstock within the reactors"

An adjective describing processes, reactions, or technologies in which heat and chemical change are directly linked — that is, chemical reactions that release or absorb heat or methods that use heat to drive a chemical transformation. It is used to label technologies (for example, fuel production, materials processing, or energy storage) where thermal energy is an intrinsic part of the chemical mechanism; it does not mean merely ‘hot’ or ‘chemical’ in isolation but the combined thermal–chemical interaction.

Completes 12-Hour Multi-Unit Campaign Using High-Value PGM-bearing Catalytic Converter Feedstock to Demonstrate Controlled Multi-Unit Operation under High-temperature Reactive Chlorination Conditions

HOUSTON, Oct. 1, 2026 /PRNewswire/ -- Metallium Limited (ASX: MTM; OTCQX: MTMCF; OTCQX ADR (MTLMY) announced it continues to prove its technology with the successful completion of its third-quarter 2026 multi-unit Flash Joule Heating (FJH) operations campaign at the Company's Texas Technology Campus.

This campaign involved three FJH reactors operating with chlorine and PGM-bearing catalytic converter material, marking an important progression from the Company's earlier multi-unit inert commissioning campaign into reactive processing. Additional details can be found here: https://asx.api.cmfyapp.com/asx-research/1.0/file/2924-03142870-6A1347079&v=undefined.

The campaign followed an earlier demonstration of three FJH reactors operating simultaneously for a sustained period of 12 hours. "This completed activity has taken the next step from simply a same multi-unit operating capacity to one that is significantly more commercially relevant for the company," said Michael Walshe, Managing Director and CEO of Metallium. He noted that this campaign was designed to generate operating and metallurgical data required to better understand the thermochemical behavior of the feedstock within the reactors and how key process variables interact under chlorination conditions.

"It is exactly how we need to develop the platform as we move toward commercialization, which we anticipate will begin sometime in the first half of 2017 as the company begins to produce saleable metal-bearing products, including metal chlorides and other intermediate forms, prior to a full-scale commercial launch next year," Walshe noted.

Metallium (https://www.metalliuminc.com) is developing and commercializing Flash Joule Heating (FJH) technology to recover critical and precious metals from mineral concentrates and selected waste streams. Through its wholly owned subsidiary, Flash Metals USA Inc., the company operates the Gator Point Technology Campus in Texas, supporting technology development, customer testwork, commercial technology services and the staged deployment of metal-processing operations.
