Mineral pigments (such as kaolin clay) having a high surface area and particle size in the nano scale range are provided which are useful in paper coating and filling, ink jet coating formulations, paint compositions, and as a filler in rubbers, plastics and polymers. These pigments are manufactured by intensive wet milling of a mineral composition which may have undergone prior dry grinding and then optionally subjecting the wet milled mineral composition to an acid treatment. |
