In a subtle yet significant pivot for Australia’s role in critical minerals, Alcoa Australia is reinventing its Western Australian bauxite assets for a much newer mission—gallium production. Today, the company made an announcement of a joint venture with Sojitz Corporation of Japan as Japan Australia Gallium Associates (JAGA), to mine and process gallium, a strategic metal increasingly central to semiconductors and visionary industries.
This isn’t just another industry experiment. Alcoa is turning what was once considered leftover material into something with serious global value—laying the groundwork for Australia to emerge as a key supplier of gallium, especially in clean energy and defence technology sectors.
Gallium: A Small Metal with Big Impact

Gallium does not appear on mining “top tens”—but it’s quietly woven into hundreds of millions of modern technologies: microchips, 5G tech, LEDs, and solar panels. It also powers high-end alloys and military electronics. Demand is developing rapidly, but global supply continues to be tightly controlled and largely reliant on China, which controls much of the market refining.
With the integration of a domestic gallium stream, Alcoa and Sojitz are achieving two strategic goals: unlinking supply chains from geopolitical risk, and providing foundation materials to industries at the epicenter of future energy and communications requirements.
From Bauxite Leftover to High-Tech Metal
What makes Alcoa’s approach unique is the use of bauxite by-product to extract gallium. Previously, gallium-containing residues were wasted or the lightly refined ones, and only a portion of their possible value was seized. JAGA’s technology changes all that. Rather than building a mine from scratch, the project introduces new value extraction onto an established refining footprint, conserving time, capital, and the environment.
A senior project manager described it simply: “We’re giving value to what was once waste—adding a clean-tech metal to our portfolio without building a new industrial base.”
Alcoa’s Western Australian Operations:
| Facility | Annual Capacity | Current Status | Potential Gallium Source |
| Pinjarra Refinery | 4.2+ million metric tons | Active | Primary target |
| Wagerup Refinery | 2.6 million metric tons | Active | Secondary potential |
| Kwinana Refinery | 2.2 million metric tons | Care and maintenance | Future potential |
Where the Magic Happens: Inside the JV
JAGA unites Sojitz’s off-take arrangements with Alcoa’s long-standing refining presence within WA. Bauxite, when refined to alumina, releases infinitesimal amounts of gallium in residue. JAGA aims to extract gallium by refining the residual material left from bauxite processing, with the end goal of supplying high-purity gallium to global markets—Japan being a major destination.
This strategy allows Australia to produce gallium on the back of negligible incremental infrastructure—a stark difference to multi-billion dollar capex for standalone critical minerals projects.
What This Means for WA Communities
Embedded in the technical is a human story: neighbourhoods resident in the bauxite districts—Pinjarra, Wagerup, and Kwinana—were now in line for new chemistry, refining, and logistics work. Local transport operators, suppliers, and regional service providers also have much to gain.
One local councillor noted, “For alumina-located towns, this could be the kick-start for the next generation of regional industry.” Parents and children alike now appreciate science labs, industrial chemistry and export logistics as career paths—connecting bauxite mining to high-tech foreign applications.

A Broader Strategic Shift
Consistent with Australia’s Critical Minerals Strategy, the partnership is proof of the shift towards downstream value capture: not just mining metals from below the ground, but cutting and exporting them. In policy circles, the move is being described as a sea change—reflecting willingness to build sovereign capacity in technology-critical metals, rather than relying on capricious global markets.
Industry veterans view JAGA as a model. They claim: If WA is able to profitably recover gallium from residue streams, other value-add projects—like rare earth separation or metal refining to battery grade—can draw upon the same playbook.
The Competitive Advantage: Low Capital, High Upside
Gallium is rare and economically difficult to refine. Rather than investing millions in new finds, Alcoa is extracting value from an existing infrastructure. The operation is also supported by Sojitz’s offtake deals—guaranteeing demand before even production begins, confirming commercial viability.
With worldwide gallium supply stretched to its limits and semiconductor demand rising, Australia is perhaps the first-mover among secure producers—far from desperation, but a shrewd utilization of existing assets.
What to Look Out for Down the Track
- Pilot Plant Progress: Will JAGA go all the way from laboratory bench to commercial scale without significant cost blowout?
- Offtake Contracts: Will JAGA secure long-term supply contracts with electronics manufacturers and national tech agencies?
- Policy Initiatives: Will Canberra introduce price support, incentives, or quotas for critical minerals to underpin such ventures?
- Technology Escalation: If this breakthrough pans out, it could open the door for Western Australia to tap into other high-value tech metals—like bismuth, germanium, and antimony—using similar recovery methods from existing waste streams.
Last Word: Alcoa’s Quiet Step into the Critical Minerals Age
Alcoa takes a quiet step into the future. WGA puts WA back on the list for driving aluminium-but not just any aluminium. A future world may see WA driving semiconductor factories and military microelectronics as significantly.
This isn’t hype-this is practical transformation, grounded in infrastructure, science and strategic foresight.
JAGA isn’t just extracting metals—it’s mining opportunity from the unlikeliest of places, positioning Australia as a smarter, leaner player in the coming mineral revolution.
