摘　　要：随着国内氧化铝产能的不断扩大和国家环保政策的陆续出台,我国铝土矿的内需存在较大缺口,进口铝土矿需求量猛增。本文通过分析进口铝土矿的特点,并结合其溶出特性,对国内老厂改用进口矿的工艺进行了探讨,希望对国内老厂改用进口矿的实际应用提供参考。With the continuous expansion of domestic alumina capacity and the introduction of national environmental protection policies,there is a large gap in domestic demand for bauxite in China,and the demand for imported bauxite has increased sharply.By analyzing the characteristics of imported bauxite and combining with its digestion features,the processes of using imported bauxite in domestic brown plants are studied,with the view of providing reference for the practical application of using the imported bauxite in domestic brown plants.
