From drivers to decliners – Unlike Q1 2025, China and Europe’s alumina output slips in April, dragging global production down

In April 2025, the world alumina production, including chemical and metallurgical-grade, totalled 12.407 million tonnes, reflecting a month-on-month downfall of 2.48 per cent from 12.723 million tonnes, found the International Aluminium Institute.
Of the total alumina output, metallurgical-grade production volume was 11.614 million tonnes, which was also down by 3 per cent M-o-M from 11.974 million tonnes. Meanwhile, the chemical-grade alumina production in April 2025 registered an increase of 5.87 per cent from 749,000 tonnes to 793,000 tonnes.
Even on an annual basis, the world’s chemical-grade alumina production grew by 3.12 per cent from 769,000 tonnes, and that of metallurgical-grade alumina output decreased by 3.83 per cent from 11.186 million tonnes.
