摘　　要：对广东某高岭土进行原矿性质分析和选矿试验研究,确定了合理的工艺流程,原矿经捣浆-除砂-φ75 mm水力旋流器提纯-磁选后,可以获得优质陶瓷用高岭土,产率为24.01%,Al_2O_3含量为37.11%,SiO_2含量为45.46%,Fe_2O_3含量为0.68%,烧成白度为90.7%,为该地区高岭土的开发利用提供了依据。Based on mineralogical analysis of the ore and experimental research of mineral processing, the reasonable process was determined. Through the process of churning-degritting-φ75 hydrocyclone purifying-magnetic concentration, a high quality kaolinite product for ceramic was obtained, with kaolinite of yield 24.01%, Al2O3 37.11%, SiO2 45.46%, Fe2O3 0.68% and firing whiteness 90.7%. This study provided basis for utilizing kaolinite of Guangdong.
