Abstract
The present invention provides a process of manufacturing co-ground calcium carbonate material made of ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC). The process includes the steps of: (a) providing GCC in an aqueous suspension; (b) co-grinding the aqueous suspension of GCC and an aqueous suspension of PCC, optionally with at least another mineral material, to obtain a co-ground calcium carbonate material having a steepness factor of at least 30; (c) optionally screening and/or upconcentrating the co-ground calcium carbonate material obtained following step (b); and (d) optionally drying the co-ground calcium carbonate material obtained following step (b) or (c).
