Advanced refining technology for germanium and gallium.

Gega Elements is building advanced refining capability for germanium and gallium, vital elements powering next-generation semiconductors across AI, electric vehicles and space, as well as fibre optic networks.

A new secure supply chain

As global demand for germanium and gallium accelerates, access to secure supply chains and refining capacity remains a major bottleneck. Gega Elements is changing that.

We have developed advanced refining technology that extracts and purifies germanium and gallium from currently underutilised mine feedstocks, including mining and refining tailings and concentrates.

The result: a clean, more efficient refining process that boosts industrial resilience and enables the industries of the future.

A cleaner, cheaper process

Our proprietary adsorption technology replaces conventional solvent extraction, delivering superior recovery rates at significantly lower cost and environmental impact.

adsorption

Advanced adsorption technology

Specifically engineered for germanium and gallium, precise, efficient, and free from toxic reagents.

feedstocks

Unlocking underutilised feedstocks

Germanium and gallium are extracted from tailings, concentrates, and ores in untapped stockpiles around the world.

Lower emissions and cost

Lower cost. Lower emissions.

~30-40% lower cost and COâ‚‚ emissions than conventional refining technology.

Refined

Refined to 99.99% purity

Exceptionally high level of refinement, one step from the final used in semiconductors, fibre optics, and advanced electronics

Scalable

Scalable & deployable

Technology is deployable at the source and can be scaled to suit, wherever germanium and gallium feedstocks exist.

Icon

The minerals behind every critical technology

Germanium and gallium are essential for the technologies reshaping the global economy, and demand is accelerating.

Artificial Intelligence

Gallium chips are replacing silicon chips underpinning the high-speed semiconductors powering AI data centres.

Permanent Magnets

Gallium improves performance of permanent magnets in EV motors and wind turbines, while reducing reliance on dysprosium.

5G & Communications

Gallium nitride amplifiers enable 5G base stations and next-generation satellite communications.

Electric Vehicles

Gallium-based power electronics improve efficiency in EV charging systems.

Space

Gallium solar cells deliver the highest efficiency for spacecraft and satellite power systems.

Fibre Optics

Germanium is critical for the optical fibre that underpins global data transmission infrastructure.

Science-driven.
Commercially proven.

Together, our leadership team combines advanced materials science with commercialisation and industry experience.
