ABSTRACT:
Disclosed herein are kaolin compositions, such as beneficiated fine sedimentary kaolin compositions. The beneficiated fine sedimentary kaolins may be obtained from the upper bed of the Rio Capim Kaolin deposit. The compositions may have at least one property chosen from a low iron content and low Hinckley crystallinity index, such as Fe2O3in an amount less than about 0.8% by weight relative to the total weight of the solids content and wherein the Hinckley crystallinity index of the kaolin is less than about 0.5. Also disclosed are products obtained therefrom, such as paint and paper coating compositions.
