ABSTRACT:
A process for beneficiating crude kaolin clay under defined conditions with a sufficient amount and concentration of aluminum chlorhydrate (0.5 to about 5.0 active wt. %) to improve the clay's ability to adsorb pitch during the process of making paper. The invention also relates to the treated clay and to the use of the clay in a papermaking process to absorb pitch and/or anionic trash.
