摘　　要：以广东某风化型高岭土为对象,进行络合还原增白。分别从草酸用量、液固比、漂白时间、矿浆p H值及保险粉用量来探索各因素对增白效果的影响,得到最优漂白条件,降低了高岭土中的含铁量,将高岭土白度从65%提高到83%左右,可用于陶瓷、造纸、橡胶等工业领域。The weathering kaolin was determined to take the complex-reduction bleaching experiment from Guangdong. This article reviews the factors affecting the white degree from five aspects, the dosage of oxalic acid, liquid-solid ratio, bleaching time, p H value of pulp, the dosage of sodium hydrosulfite, and ultimately getting the best condition, lowed the dosage of iron in kaolin, thus increased the white degree from 65% to 83%, and this product may be used in ceramic area, paper-making industry, rubber industry and so on.
