Korea Zinc weighs Australia expansion amid critical minerals push - The Korea Herald

Korea Zinc is considering an expansion of its Australian operations as part of a broader strategy to secure critical minerals supplies. The company, which refines zinc and recovers by-product metals, is evaluating opportunities in Australia amid growing global demand for materials needed in the energy transition.

Where this fits

This story touches the materials and sovereignty pillar of Australia's energy transition. A renewables-heavy grid requires vast quantities of zinc (galvanising transmission steel), lithium, cobalt, nickel and rare earths for batteries, inverters and motors. Korea Zinc's interest in Australian expansion is positive, it represents supply-chain diversification away from China's near-total dominance in mineral processing. But the headline masks a harder truth: Australia produces raw ores, China processes them into grid-ready components at scale and cost Australia cannot yet match. An Australian zinc refinery is necessary but not sufficient; the bottleneck is downstream battery cells, inverters and modules, which remain concentrated in China's coal-powered factories.

What it means

If Korea Zinc commits to Australian refining, it chips away at processing dependence on a strategic rival. That is real gain for grid security and national sovereignty. But it does not solve the embedded-emissions problem: China's coal-fired battery gigafactories will remain the pathway for most of Australia's solar and storage hardware for the next decade. A firm, energy-dense alternative, nuclear, requires no exotic minerals, no battery supply chains, and far lower downstream processing demand. The transition Australia is building is material-hungry and China-dependent by design. Diversifying to Korea does not change that structural fact.
