According to the International Aluminium Association, metallurgical-grade alumina output was 21.3 million tonnes in the first quarter of 2025, then dipped a little in Q2 to 21 million tonnes, only to jump noticeably in Q3, reaching 22.7 million tonnes — an 8.17 per cent increase from the previous quarter.
Compared with last year’s third quarter, when China produced 20.91 million tonnes, the latest Q3 total stands 8.86 per cent higher.
The monthly trail reveals how the turnaround took shape. January opened at 7.306 million tonnes, but February sank to 6.745 million tonnes — roughly a 7.7 per cent fall — before production bounced back to 7.325 million tonnes in March, up 8.6 per cent. April dipped again to 6.878 million tonnes, though May and June clawed back the loss with 7.040 million and 7.125 million tonnes respectively. Things steadied more in the third quarter: July registered 7.581 million tonnes, August edged higher to 7.629 million tonnes, and September eased slightly to 7.553 million tonnes. In short, a shaky opening, a methodical mid-year rise and then a fairly level line heading into autumn.
