摘　　要：In light of the problems of low-quality and low degree of comprehensive utilization of Guangdong muscovite-type kaolin, the reasons affecting the quality of kaolin were found to be a small amount of maroon powdery goethite adhering to the surface of kaolin and minor muscovite affecting the firing whiteness of products. The ores were dealt with by using the new combined process of attritioning-classifieation-bleaching and flotation. The separation of kaolin from muscovite, quartz and feldspar can come true through the new process. The high-quality kaolin with the firing whiteness of 91% can be obtained, and the muscovite is comprehensively recovered by adopting the key technology of flotation. The content of high-purity muscovite produced is over 99%. The muscovite discarded by original process can be comprehensively recovered.In light of the problems of low-quality and low degree of comprehensive utilization of Guangdong muscovite-type kaolin,the reasons affecting the quality of kaolin were found to be a small amount of maroon powdery goethite adhering to the surface of kaolin and minor muscovite affecting the firing whiteness of products.The ores were dealt with by using the new combined process of attritioning-classification-bleaching and flotation.The separation of kaolin from muscovite,quartz and feldspar can come true through the new process.The high-quality kaolin with the firing whiteness of 91%can be obtained,and the muscovite is comprehensively recovered by adopting the key technology of flotation.The content of high-purity muscovite produced is over 99%.
