High-aluminum clay ores are protective exploitation ores given by the Ministry of Land and Resources ,which have played an significant role in social economic development and military use .However , due to its physical and chemical properties ,mineral features and current mineral classification ,high-aluminum clay ores are used as normal refractory clay in practical application which does not optimize the use of resources and results in huge waste of it .By analyzing the differences and similarities between high-aluminum clay and refractory clay and bauxite in the way of mineral composition ,petrochemistry ,physical structure and etc .,this paper proves that the physical and chemical properties ,mineral characteristics and etc .of high-aluminum clay ores achieve the standards of industrial index of bauxite .So the authors believe that high-aluminum clay ores should be classified into bauxite .Meanwhile ,this paper also puts forward improvements and normalization of high-aluminum clay ores exploitation combining with present situation of its investigation and development in Henan province .%高铝黏土是国土资源部规定的保护性开发矿产，在社会经济发展和军事利用方面都具有重要的作用，但由于其理化性能、矿石特征与现行的矿石类型归属---耐火黏土矿有较大不同，在实际应用中常将高铝黏土当作一般耐火黏土矿来使用，从而导致大量高铝黏土没有得到优质优用，造成高铝黏土资源极大的浪费。本文通过剖析高铝黏土在矿物组分、岩石化学、物理结构等方面与耐火黏土矿和铝土矿之间的差异与形似性，证明其理化性能、矿石特征等均能达到铝土矿工业指标要求，应考虑将其归类为铝土矿的一种，并结合河南省的高铝黏土勘查开发现状进行实证分析，进而完善高铝黏土勘查规范。
