摘　　要：简要介绍了我国铝土矿资源特点及氧化铝工业现状,扼要分析了用一水硬铝石型A/S:5-7铝土矿生产氧化铝的艺方案。采用最简单的纯拜耳法处理一水硬铝石型A/S:5-7铝土矿生产氧化铝时,加入新型溶出添加剂获得了从未有过的最佳溶出效果,并列出了主要溶出条件和溶出效果。A brief introduction to the characteristic of our country is made in this paper. And it is mainly analysed that using a type of A/S：5～7 water-bauxite to produce alumina was technically schemed. When the bauxite was used to produce alumina with the simplest pure Bayer process, an unprecedented and best effect of digest has been obtained as the new additive of digest added. The major condition and effects of digest is listed here.
