氧化铝生产消耗大量的能源。但由于处理原料的矿物类型和化学组成不同,各种方法生产氧化铝的能耗差异亦甚大。一般来说,每生产一吨氧化铝消耗0.285～1.714吨标准煤,总能耗占氧化铝产品费用的7～55％。表1示出国内外各种方法生产氧化铝的能耗。

Alumina production consumes a lot of energy. However, due to the different mineral types and chemical composition of raw materials, the energy consumption of various methods for producing alumina is also very different. Generally speaking, each ton of alumina produced consumes 0.285-1.714 tons of standard coal, accounting for 7-55% of the total cost of alumina products. Table 1 shows the energy consumption of various methods of producing alumina at home and abroad.
