摘要
发展我国氧化铝工业，除积极努力寻求适合我国-水硬铝石型铝土矿特点的生产方法之外，亦不可忽视非铝土矿含铝资源（明矾石、霞石正长岩、富钾边外铝土矿等）的综合利用或铝土矿的联合开发。综合利用这些原料，除产出氧化铝之外，还可产出钾产品、水泥、免蒸免烧砖等。预计这些产品市场前景非常广阔，经济效益也相当好，它将成为我国氧化铝发展一个重要途径。
To develop our alundna industry,boide seeking a process amenable to the characteristics of our diaspore, it is advisable not to neglect comprehensive utilization of nonbaurite-ore sources(such as alunite, nepheline syenite and potassium enriched outer-edal ban-cite, etc) or combined development of batalte. By comprehensive uttiliZation of these material, it is possible to ploduce not only alumina, but also potassium preduct, cement and bricks free fIDm evaporahon and buming. A broad market pmepet and good economic efficiency of these products can be expected,thus opening up an important way to develop China's alumina industry.
