Abstract:
The present invention relates to a process for the manufacturing of a calcium carbonate-comprising material, to a calcium carbonate-comprising material obtained by the process as well as the use of the calcium carbonate-comprising material for paper filler and paper coating applications, in plastics applications, in paints, in adhesives, in sealings, in concrete, in agriculture applications, in food applications, in cosmetic applications or in pharmaceutical applications.

Claim (Index 1):
A calcium carbonate-comprising material obtained by the process comprising the steps of:\n a) providing at least two aqueous suspensions comprising a calcium carbonate-comprising material, wherein:\n i) the first aqueous suspension has a solid content from 1.0 to 82.0 wt.-%, based on the total weight of the aqueous suspension, and a content of particles having a particle size <2 \u03bcm in the range from 1.0 to 30.0 wt.-%; and \n ii) the second aqueous suspension has a solid content from 10.0 to 82.0 wt.-%, based on the total weight of the aqueous suspension, and a content of particles having a particle size <2 \u03bcm in the range from >30.0 to 100.0 wt.-%; \n b) mixing the at least two aqueous suspensions provided in step a) to obtain an aqueous suspension mixture; c) grinding the aqueous suspension mixture obtained in step b) to obtain a ground aqueous suspension mixture; d) optionally concentrating the ground aqueous suspension mixture obtained in step c) to remove at least a portion of water by mechanical means to obtain a partially dewatered calcium-carbonate material; e) optionally drying the ground aqueous suspension mixture obtained in step c) or the partially dewatered calcium-carbonate material obtained in step d), if performed, to obtain a dried calcium carbonate-containing material; and f) optionally treating the dried calcium-calcium carbonate material of step e) with at least one saturated aliphatic linear or branched carboxylic acid and/or with at least one mono-substituted succinic anhydride and/or at least one mono-substituted succinic acid and/or salty reaction product(s) and/or with at least one phosphoric acid ester blend of one or more phosphoric acid mono-ester and/or reaction products thereof and one or more phosphoric acid di-ester and/or reaction products thereof to obtain a hydrophobized calcium carbonate-comprising material.
