Notes
Planned/under construction. Gallium plant co-located at Alcoa's Wagerup alumina refinery (WA), ion-exchange extraction from refinery process liquor. FID + construction began Aug 2026; ~100 t/yr (~10% of world supply); first production Q4 2026. Part of the Australia-US Framework for Critical Minerals. Alcoa and its Australian, Japanese and US government partners held the groundbreaking for the gallium plant co-located at the Wagerup alumina refinery in August 2026, so the project is in construction rather than merely planned. The factsheet gives 100 t/yr capacity, ion-exchange recovery from up to 10 per cent of the refinery liquor stream, and a joint venture with Japan Australia Gallium Associates (Sojitz and the Japanese Government).
