Kaolin may be used as a group name for clay minerals, encompassing the phyllosilicates kaolinite, dickite, nacrite, and halloysite with its metaforms, allophane and imogolite. It is synonymous with the group term kandites which is un-approved and seldom used in the literature, but mentioned here for completeness.

The mined kaolin is usually associated with various impurities like quartz, anatase, rutile, pyrite, siderite, feldspar, etc., depending on the origin and depositional environment (Grimshaw, 1971). These impurities impair the characteristics of a kaolin and effect its utility for various end applications.
