Since mid-April, the operating capacity of alumina in China has remained at a relatively low level. As a result, the supply-side gap has been continuously reflected. Coupled with the impact of sudden uncertainties at the Guinea mine, the futures and spot prices of alumina in China have risen simultaneously. The suspension of mining in Guinea is still expanding its impact. It is not ruled out that the operation of other mines will also be restricted in the future. Therefore, from the perspective of raw material supply and the market situation of alumina itself, it will continue to be beneficial to the spot price of alumina in the short term.
