Lithium Universe Expands Lab Tech to Extract Gallium and Platinum From E-Waste
Lithium Universe Limited (ASX: LU7) has announced the acquisition of an exclusive worldwide licence for a patented gold and copper extraction technology developed by the University of Edinburgh's School of Chemistry. Known as the Gold Copper Diamide Extraction (GCDE) process, the technology selectively recovers gold and copper from electronic waste—including computers, mobile phones, and printed circuit boards—using simple, reusable organic compounds at room temperature, without energy-intensive smelting or toxic chemicals.
The announcement marks a significant strategic expansion for LU7, adding a second high-value metals recovery capability to its growing Precious Metals Recovery Division, alongside its existing silver extraction technology for end-of-life solar panels. The Lithium Universe e-waste gold and copper recovery technology licence with University of Edinburgh establishes exclusive global rights to commercialise a peer-reviewed, patented process that targets what industry experts call "urban ore."
To understand why this acquisition matters, consider the scale of the problem it addresses.
E-waste is now the fastest-growing hazardous solid-waste stream on the planet. Global generation is forecast to reach 93.5 million tonnes by 2030, up from 62 million tonnes in 2022—a rise of approximately 32% in under a decade. Yet only around 20% of e-waste is formally recycled using environmentally responsible methods. The remaining 80% ends up in landfill or is exported to developing nations for crude processing that releases toxic pollutants.
What makes this particularly striking for investors is the extraordinary metal content sitting inside that discarded waste:
| Metal | Concentration in E-Waste | Current Market Price | Value Per Tonne of E-Waste |
|---|---|---|---|
| Gold | 200–350 g/t (avg. 300 g/t) | US$4,800/oz | US$46,320/t |
| Copper | 50–270 kg/t (avg. 160 kg/t) | US$12,900/t | US$2,064/t |
| Combined | ~US$48,384/t |
For context, the gold content alone in e-waste—at 200–350 grams per tonne—is up to 100 times higher than the concentration found in natural gold ore. In waste mobile phones specifically, gold concentrations can reach 1,200 g/t. Printed circuit board streams can carry up to 900 g/t of gold.
Copper, furthermore, forms the backbone of circuitry and can represent up to 20% by weight of waste printed circuit boards. This is what the industry calls **"urban ore"**—and most of it is currently being buried.
The GCDE technology is a water-based metal extraction process that recovers gold and copper in two sequential stages, each using a specially designed organic molecule to selectively bind and remove the target metal from an acidic solution.
Electronic circuit boards are first processed through conventional shredding and separation equipment, producing a concentrated printed circuit board stream. This stream is then treated at room temperature using an acid solution containing chloride compounds, dissolving the metals into solution as soluble metal complexes.
A specially engineered organic compound called a diamide—a small, reusable molecule—is introduced into the solution. The diamide selectively recognises and binds gold ions, causing the gold-diamide complex to precipitate as a distinct yellow solid, while base metals including copper, iron, and nickel remain dissolved in solution.
The gold complex is then washed to produce a pure HAuCl₄ solution, which is refined to metallic gold. Critically, the diamide reagent is recovered and reused multiple times, reducing ongoing reagent costs. The process operates without cyanide, mercury, or organic solvents—a meaningful environmental advantage over conventional methods.
After gold removal, the remaining acidic solution—rich in dissolved copper—is treated with pyrazine-2,3-dicarboxylic acid (PDCA), a selective copper binding agent. PDCA forms strong bonds with copper ions, creating a stable complex that precipitates selectively from the mixed-metal solution.
Copper is then released from the binding agent through electrical or chemical treatment. Because this step occurs after gold removal, metal purity is high and cross-contamination between metals is minimised.
Key Process Advantages at a Glance:
The dominant method for recovering gold from e-waste today is high-temperature smelting—a process that involves shredding waste and feeding it into furnaces operating at 1,200–1,400°C, where plastics combust, base metals melt, and gold concentrates in a copper alloy before being separated through electrical refining.
| Feature | Conventional Smelting | GCDE Process |
|---|---|---|
| Operating temperature | 1,200–1,400°C | Room temperature |
| Energy intensity | Very high | Low |
| Toxic reagents | Yes (cyanide, mercury) | No |
| Selectivity | Low (bulk extraction) | High (targeted metal recovery) |
| Reagent reuse | No | Yes (diamide is recyclable) |
| Suitable for small scale | No | Yes |
| Environmental impact | High | Low |
| Capital cost | High | Comparatively low |
The GCDE approach, however, represents a fundamental shift from bulk thermal processing to precise, low-energy molecular chemistry—a distinction that carries both environmental and economic implications.
Water-based metal extraction (hydrometallurgy) is a branch of metallurgy that uses water-based chemical solutions—rather than heat—to extract metals from ores or waste materials. Instead of melting everything in a furnace, metals are dissolved into solution and then selectively recovered using chemical agents.
A selective binding agent is a molecule that attaches to a specific metal ion, forming a complex. Think of it like a molecular lock and key—a well-designed binding agent will selectively attach to one metal while leaving others untouched. In the GCDE process, the diamide compound is the "key" that only opens the "lock" of gold ions.
Selectivity is the core economic advantage of the GCDE process. In conventional smelting, everything is melted together and then laboriously separated. In the GCDE process, gold is captured cleanly in Stage 1 and copper in Stage 2. This staged, selective approach reduces downstream refining complexity and improves the purity—and therefore the value—of the recovered metals.
The GCDE technology was developed by Professor Jason Love and Professor Carole Morrison of the University of Edinburgh's School of Chemistry. Their foundational work was published in the prestigious journal Nature Communications in 2021, and a patent application covering Europe and the United States was filed in 2022. Both professors are recipients of the Anders Gustav Ekeberg Prize (2020).

The Company brings significant experience in scaling innovative processing technologies from laboratory development through to commercial deployment. There are clear synergies with Lithium Universe's existing silver extraction technology and its strong chemical engineering and project delivery expertise. We will work closely with the Company to advance the development of a pilot plant and accelerate the pathway to commercialisation." — Professor Jason Love, University of Edinburgh
The GCDE acquisition does not represent a departure from LU7's core strategy—it is, in fact, a deliberate extension of it. LU7 is building two parallel divisions.
LU7's primary focus remains the development of merchant lithium carbonate refineries in North America—specifically its planned projects in Bécancour, Québec, and Brownsville, Texas—targeting battery-grade lithium carbonate production of up to 18,270 tonnes per year per facility.
This division now encompasses two technology licences:
Both divisions operate on a shared philosophy: the energy transition creates not only demand for new materials but also growing streams of end-of-life equipment containing valuable metals that can and should be recovered.
"Our strategy is built around two complementary divisions, each addressing critical gaps in the global energy transition… This division is driven by a simple rationale: the energy transition is not only about producing new materials, but also recovering valuable metals already in circulation." — Executive Chairman Iggy Tan
LU7's stated next steps for the GCDE technology centre on advancing from laboratory scale toward pilot plant development. The milestone payment structure embedded in the licence agreement maps the commercialisation pathway clearly:
| Milestone | Trigger | Payment to Edinburgh |
|---|---|---|
| Pilot Plant FID | Final Investment Decision | £100,000 |
| Commissioning | Plant start-up | £100,000 |
| First Commercial Sale | Initial revenue event | £100,000 |
Beyond these milestones, the broader strategic optionality highlighted by management includes the potential to sublicence the GCDE technology to third parties—a model under which LU7 would retain 80% of royalty income while Edinburgh University receives the remaining 20%.
Several factors combine to make this announcement worth careful attention:
Exclusive global rights to a peer-reviewed, patented technology—published in Nature Communications and developed by award-winning university researchers, independently validated by the academic community.
Capital-light entry point—the initial licence costs represent a modest outlay for worldwide exclusivity, with milestone payments tied to commercial progress rather than front-loaded capital commitments.
Massive and growing addressable market—93.5 million tonnes of e-waste generated annually by 2030, with 80% currently unrecycled, representing substantial untapped revenue potential.
Complementary technology stack—the Lithium Universe e-waste gold and copper recovery technology licence with University of Edinburgh sits alongside LU7's silver extraction technology, creating a multi-metal precious metals recovery platform.
Sublicensing optionality—the ability to sublicence the technology globally means LU7 can pursue asset-light revenue streams without needing to build every facility itself.
Dual-division structure with built-in optionality—management has explicitly flagged the Precious Metals Recovery Division as a potential standalone entity that could be spun out, representing a distinct value unlock pathway for shareholders.
In summary, the acquisition positions LU7 as a technology licence holder for one of the world's most metal-rich waste streams. For investors tracking companies positioned to benefit from growing volumes of end-of-life electronic equipment, this represents a compelling addition to LU7's investment thesis.
