摘要
在铝土矿矿石结构分类（粗糙状、碎屑状、鲕豆状和致密状）的基础上，根据拜尔法工艺对矿石的要求，按矿石中主要组分的种类及其含量进一步划分为正常型、高岭石型、伊利石型、绿泥石型和混合型五个亚类。利用矿石中的Ａｌ２Ｏ３、ＳｉＯ２、Ｋ２Ｏ、Ｆｅ２Ｏ３和ＴｉＯ２，根据Ｑ型聚类分析划分了三种化学成分类型。对不同矿石类型的可用性提出了结论性意见。
On the basis of texture, bauxite ore divided into five subtypes of the normal,the kaolinite,illite,chlorite and the mixed, in accordance with the species and amount of the major components in the ore.Q-mode cluster analysis is made from Al2O3, SiO2,K2O,Fe2O3 and TiO2 in the researched specimens.The results give a suggestion on the suitability of various bauxite ore types.
