Abstract
The present invention relates to a process for the preparation of an aqueous suspension comprising at least one calcium carbonate-comprising material, the calcium carbonate-comprising material having a ratio of particles having an average particle size d80 value to particles having an average particle size d20 value [d80/d20] in the range from 1.5 to 4 and the use of the calcium carbonate-comprising material in paper and board applications, in cosmetics, in caulks and sealants, in adhesives, in paints and coatings, in fibre applications, in plastics applications or for the replacement of PCC in general.
