The method according to claim 1 , wherein more than 0.01 wt % and less than 90 wt % of pigments coated in an acid-resistant manner are used.4. The method according to claim 1 , wherein more than 85% of the outer surface of the acid-soluble pigments are covered by the organic compound melting at T>200° C.5. The method according to claim 1 , wherein the organic compound melting at T>200° C. is vapor-deposited onto the acid-soluble pigments.6. The method according to claim 1 , wherein the mass ratio of the organic compound melting at T>200° C. to the acid-soluble pigments is in a range of 0.07 to 0.2.7. The method according to claim 1 , wherein ...

DRYING PROCESS

The present invention refers to a process for making a calcium carbonate containing material, wherein the process includes a specific drying procedure and allows for the provision of calcium carbonate materials with reduced moisture pick-up and low porosity. 19-. (canceled)10. A calcium carbonate containing material obtainable by a process comprising the following steps: i) having a moisture content of more than 65 wt.-%, based on the weight of the moist calcium carbonate containing material, and', 'ii) containing no dispersant or containing a sub-effective amount of dispersant;, 'a) providing a particulate moist calcium carbonate containing material, said material'}b) reducing the moisture content of the moist calcium carbonate containing material of step a), thereby removing a part of the water soluble matter present in the Particulate moist calcium carbonate containing material, wherein the moisture is removed with mechanical means at a temperature in the range of more than 0° C. to 65° C. in one or more steps by at least 10% and in any case to a reduced moisture content of less than 65 wt.-%, based on the weight of the moist calcium carbonate containing material;c) thermally concentrating the moist calcium carbonate containing material with the reduced moisture content of step b) at a temperature in the range of −100° C. to 100° C. until a final moisture content of not more than 1.0 wt.-%, based on the weight of the calcium carbonate containing material.11. A calcium carbonate containing material obtainable by a process according to claim 10 , wherein the calcium carbonate containing material obtained in step c) is treated with a hydrophobizing agent claim 10 , and wherein the calcium carbonate containing material has a moisture sorption susceptibility of less than 0.8 mg/g claim 10 , preferably of less than 0.6 mg/g claim 10 , even more preferably of less than 0.5 mg/g and most preferred of less than 0.3 mg/g.12. A calcium carbonate containing particulate ...
