摘　　要：锦州煤系高岭岩属古生代浅变质岩系 ,高岭石的矿物形态为片状、鳞片状。主要矿物高岭石含量 >90 % ,杂质矿物为石英、赤铁矿及褐铁矿、碳酸盐类矿物、金红石等。利用先超微细磨矿后煅烧工艺 ,获得了白度 92 .1%、- 2 μm含量 91.8%的“双 90”级煅烧高岭土产品。产品性能达到造纸涂料要求。Jinzhou coal-series kaolin rock belongs to Paleozoic epizonal metamorphism rock series. The kaolinite is schistose and scaly shape. The kaolin content in the ore is over 90%, and impure minerals include quartz, hematite, limonite, carbonate minerals and rutile etc.. In this research, the 'double 90' calcined kaolin product with a whiteness of 92.1% and content of 91.8% with size -2μm was produced. And the product performance can meet the need of paper coating.
