Jul. 18, 2025 - China's total alumina output, including smelter-grade alumina and other types, rose by 9.3% year-on-year to reach 45.15 million tons during the first half of 2025, according to the latest data released by the country's National Bureau of Statistics (NBS).

In June alone, China produced 7.75 million tons of alumina, up by 3.5% from May and by 7.8% from the same month last year, the NBS data showed.

East China's Shandong province, North China's Shanxi province, and Southwest China's Guangxi Zhuang autonomous region remained the country's top three alumina-producing regions last month.

Alumina production in Shandong and Guangxi grew by 3.4% and 4.3% respectively from May to reach 2.76 million tons and 1.47 million tons in June. In contrast, Shanxi's output of 1.67 million tons in June saw a marginal drop of 0.05% from the previous month.

Central China's Henan province and Southwest China's Guizhou province ranked fourth and fifth nationwide in June in terms of alumina output by producing 735,400 tons and 501,400 tons respectively, with marked on-month increases of 11.9% and 11.8%.

Notably, Southwest China's Yunnan province posted the highest month-on-month growth among all production bases with monthly output exceeding 100,000 tons in June, with its volume jumping by 19.8% to 107,500 tons, despite ranking only seventh in output.

The month-on-month increases in production across various areas in China were largely driven by the resumption of operations at alumina refineries, spurred by continued improvements in their profit margins, according to market analysts.

The average profit margin among 44 typical Chinese alumina producers surged by 105% from May to Yuan 391.4/ton ($54.4/t) in June.
