| Abstract: | Because high-iron and low-grade kaolin in Hepu Guangxi is a high iron content,in the ore Fe2O3+TiO2>2.5%.After washing,in-0.045mm size fraction of the iron content of greater than 4%.Research shows that,by high gradient magnetic separation,heating bleaching methods can be obtained Al2O3>35%,Fe2O3<1.5%,greater than 80% of whiteness bleaching products. |
