摘要
Process for Manufacturing Co-ground Calcium Carbonate Material, Co-Ground Calcium Carbonate Material, and Use of Co-Ground Calcium Carbonate Material An object of the present invention is to provide a process for obtaining a co-ground calcium carbonate material. calcium comprising GCC and PCC, having a fraction of particles finer than 1 µm of greater than 80%, preferably greater than 85%, more preferably greater than 90%, and even more preferably higher. than 95%, and a specific surface area of less than 25 m2 / g in a cost-efficient manner in which GCC and PCC are co-milled, possibly with at least one other mineral material. Another object of the present invention is based on co-ground calcium carbonate material in the form of an aqueous suspension and as a dry product. Another object of the present invention is based on the uses of such products in any sector making use of mineral material, and notably in the paper, ink and plastic industries.
