Abstract ：
Kaolin, a versatile material, is widely utilized owing to its distinctive mineralogical characteristics, mineral morphology, and chemical and physical properties. Whiteness, a critical factor in determining the commercial value of kaolin, is significantly influenced by its impurities. Consequently, impurity removal from kaolin has emerged as a primary research focus. These studies have concentrated on enhancing kaolin's whiteness by optimizing critical parameters and employing innovative separation techniques. On this basis, this article reviews various methods for removing and separating iron (free and structural) and carbon impurities from kaolin, detailing the technical principles, optimizing parameters, and elucidating the mechanistic features of different beneficiation methods.In addition, this paper discusses the merits and limitations of these methods and proposes potential future research directions. This paper aims to guide the selection and development of strategies for kaolin purification and the decontamination of other clay minerals.
