摘要
我国铝土矿属高铝、高硅的一水硬铝石型铝土矿，资源丰富，但铝硅比低，氧化铝溶出性能差，碱耗、能耗高，生产成本高。鉴于我国的铝土矿资源特点，采用选矿预处理＋拜耳法工艺是必要的。
China is rich in bauxite resources, but our resources is diaspore with low ratio of A/S. The bauxite digests difficultly and with high cost and expenditure of energy and base. In view of the characteristics of our bauxite resources, it is necessary to apply 'pretreatment by dressing + Bayer process'.
