This paper studied the puriifcation of washed arenaceous kaolin clay from Australia. The ore treated by sand removing with centrifugal classiifcation gets the kaolin concentrate with recovery and total recovery of 58.5% and 28.1% respectively, the content of SiO2 reduced from 52.4%to 47.2%,Al2O3 content increased from 36.5% to 38.0%. The kaolin concentrate then is chloridizing roasted to remove iron and titanium, the content ofFe2O3 andTiO2 is reduced from 1.26% and 1.03% to 0.35% and 0.46% respectively. The ifring whiteness of ifnal kaolin concentrate increased from 86.3% to 93.6%, reaching ZT-(D)1-grade national standard of calcined paper coating kaolin.
