After the start of production capacity of alumina, there is an expected increase, but it will take some time to have an impact on the price. Coupled with the fact that the cost still has an upward expectation, it is expected that the price of alumina will continue to rise in the short term. In the long term, the increase in supply is bearish for the price of alumina. At the same time, the relatively low price of imported alumina also imposes certain restrictions on the price of alumina in China.
