摘　　要：该文通过化学分析、差热分析和Ｘ射线衍射分析，对３种典型铝土矿进行了深入、系统的研究，给出了其主要化学成分、溶出率的测定结果、最佳焙烧温度，焙烧脱水相转化情况和焙烧脱水前后的物相组成；从理论上阐明了不同类型铝土矿的酸溶规律，得出了酸溶条件，扩大了原料来源。hrough chemical analysis, differential thermal analysis,X-ray diffractionanalysis,by making a further and more systematic study of three kinds of representativebauxite,the paper illustrates their main chemical elements,measured result of disolvingrate,the best baking temperature, the transforming of baking dehydration and the beforeand-after-dehydration feature-structure,In doing so,the paper has theoretically expoundedthe law of acid disolving of different bauxite,given out the acid disolving condition and expanded the sources of the materials。

关 键 词：铝土矿 差热分析 化学成分 溶出率 最佳焙烧温度
