The concentrated production reduction due to the phased maintenance of alumina plants and the need for aluminum plants to prepare for inventory around the May Day holiday have led to a short-term fluctuation and strong trend in alumina prices. However, the fundamental momentum is slightly insufficient, mainly because it is widely rumored in the market that the prices of several minerals have begun to decline relatively significantly, and there is an expectation of cost reduction in the market. From a quantitative perspective, the price level of several minerals at 75 to 80 US dollars is generally between 3,000 and 3,150 yuan compared to the cost of Jinyu alumina. Currently, the excessive decline in alumina prices has partially pre-confirmed the trend of several minerals. There is still considerable resistance for the price of several minerals to drop to around 70 US dollars in the future, which requires time for verification.
