对一水硬铝石和高岭石的晶体结构及表面性质进行总结和归纳，对高岭百颗粒的分散与聚四行为进行试验研究和理论计算，旨在为我国一水硬铝石型铝土矿的有效分选提供基础资料。高岭石是典型的具有１：１型层状结构的铝硅酸盐，其溶液特性及荷电性质对颗粒的分散与聚团行为具有重要影响，实现一水硬铝石与高岭石有效分选的重要前提之一是调节其表面性质，实现体系高效分散。
The crystal structure and surface properties of diaspore and kaolinite are summarized and summarized. The experimental study and theoretical calculation of the dispersion and polytetrafluoroethylene content of kaolinite particles are carried out. Effective sorting of mines provides basic information. Kaolinite is a typical aluminosilicate with a 1: 1 layered structure, and its solution properties and charging properties have an important influence on particle dispersion and agglomeration behavior, which makes diaspore and kaolinite effective One of the important preconditions for sorting is to adjust the surface properties of the system and to achieve efficient dispersion of the system.
