摘　　要：内蒙古鄂尔多斯煤系高岭土,因含有较多腐殖质、炭质而呈紫褐色,又称紫木节高岭土。以鄂尔多斯紫木节高岭土为研究对象,对其进行除铁增白试验研究。采用"捣浆-磁选-漂白"工艺流程,可使高岭土煅烧白度由59.49%提高到85.87%,Fe2O3含量从1.38%降到0.74%,达到搪瓷工业一级高岭土(TT-1)的标准。Inner Mongolia Erdos coal kaolin, because it contains more humus and carbonaceous which make it show the purple-brown, it also called purple kibushi kaolin. The Erdos purple kibushi kaolin was determined as the object of study, and it＇s iron removal and bleaching experiments were studied. The use of ＂chopped-magnetic-bleaching＂ process, allows Erdos purple kibushi kaolincalcined whiteness increase from 59.49% to 85.87%, the content of Fe2O3 down from 1.38% to 0.74%, and it reaches the first standard of enamel industry.
