Due to factors such as the complex application of ores, the still high prices of in-use ores, and severe losses, the production reduction of some production lines of alumina enterprises has significantly increased recently, providing certain support for the price of alumina in the short term. At a time when enterprises are concentrating on reducing production and before the newly added capacity forms an effective incremental supply, the supply is narrowing in a phased manner, and the price of alumina is expected to fluctuate upward in the short term.
