Korea Zinc Recovers Rare Earth Metals From Old Electronics

Your old smartphone might hold the key to powering tomorrow's technology, thanks to a recycling breakthrough from Korea Zinc.

The Seoul-based metals company announced it has successfully developed technology to extract rare earth elements from discarded electronics. After three years of focused research, the company can now recover valuable metals from the magnets inside waste motors, generators, smartphones, and even missile sensors.

Rare earth elements are 17 special metals that power everything from electric vehicles to wind turbines to smartphones. Right now, most countries depend heavily on mining new materials, which creates supply chain vulnerabilities and environmental concerns.

Korea Zinc's process pulls these valuable metals from used magnets and transforms them into materials ready for reuse in high-tech industries. The company collects discarded magnets from dismantled electronics, then extracts mixtures containing the 17 rare earth elements that can be refined into oxides.

The project kicked off in late 2022 when Chairman Yun B. Choi directed the company to prioritize rare earth technology. The company recruited specialists and accelerated research at its Onsan smelter research institute, working alongside in-house engineering teams.

The Ripple Effect

This technology could reshape how countries think about resource security. Instead of relying solely on mining operations, nations can tap into the treasure trove of metals already sitting in landfills and recycling centers.

Korea Zinc plans to scale the technology for commercial production while partnering with the government to secure steady supplies of discarded electronics. Company representatives say their world-class smelting capabilities will help them rapidly move from breakthrough to mass production once they establish reliable access to waste materials.

The timing matters. As the world pushes toward clean energy and electric vehicles, demand for rare earth metals continues climbing. Finding ways to recycle these materials helps countries build more resilient supply chains while reducing the environmental impact of mining.

Every discarded phone and broken motor becomes a potential source of materials for the next generation of clean technology.
