富含黄铁矿高岭岩选择性粉碎及解离机理

对未经氧化的含黄铁矿高岭岩，选择性粉碎的目的是解离并分选出黄铁矿及其聚合体。拣选交配置具有排碴装置的冲击式粉磨机是实现选择性粉碎的有效途径。文中从晶体化学的角度，应用料层粉碎理论，探讨选择性粉碎机理。

Selective Comminution and Liberation Mechanism of Pyriterich Kaolinite

For pyritecontaining unoxidized kaolinite,the selective comminution aims at liberating and separating pyrite and its interlocking minerals.An efficient way to realize the selective comminution is to use impact pulverizing mill with hardtogrind minerals discharging device.From the viewpoint of crystal chemistry,the selective comminution mechanism is discussed by applying partical layer comminution theory.
