ABSTRACT:
A method of preparing a mineral which is suitable for use in the coating of paper includes the steps of (i) forming a substantially uniform suspension of fine particles of the mineral in water; (ii) admixing the suspension thus obtained with a water-soluble or water-dispersible polymer which is such that, on dewatering and drying the suspension, the particles of the mineral adhere to the polymer and to one another and the polymer is rendered irreversibly insoluble and non-dispersible in water; and (iii) dewatering and drying the suspension to form the desired mineral.
