摘　　要：本文简要介绍了循环效率是氧化铝生产中一项非常重要的降低成本的手段,提高循环效率在相同的条件下相应提高产量,因而可以提高生产效率、降低固定成本分摊。在相同的温度体系条件下,提高拜耳法循环效率,可以使每一个立方的循环母液处理更多的铝土矿,而几乎消耗相等的能量,从而多产出氧化铝,提高生产效率,增加产量,摊薄固定成本分摊。This paper briefly introduces that recycling efficiency is a very important means to reduce cost in alumina production. To improve recycling efficiency under the same conditions, the output should be increased accordingly. So it can improve production efficiency and reduce fixed cost allocation. Under the same temperature system, increasing the cycle efficiency of Bayer process can make each cubic circulating liquid process more bauxite and consume almost equal energy, thus producing more alumina, increasing production efficiency, increasing output and reducing the fixed cost allocation.
