摘要

Removing coloring components made of kaolin, comprises: dispersing a crude kaolin in an aqueous liquid to form an aqueous suspension having a conductivity of = 600 mu S/cm (20[deg] C); centrifuging the suspension for a particle size classification, where it forms coarse fraction and a fine-fraction; separating the fractions; and obtaining the clay from the coarse fraction.
