The unground kaolin can e.g. be the recovered product from a centrifuge separation incident to beneficiation of a kaolin crude, and has a titania content of less than 2%. The unground kaolin is already of reduced particle size (e.g. being the fine cut from centrifuging, such as 92%<2 μm), and as is known, will therefore be relatively free of ...

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.
