Claim:
1. A process for remineralization of feed water comprising the steps of: a) providing feed water in need of remineralization, wherein the feed water has a concentration of free carbon dioxide of 20 to 60 mg/l that is not a result of addition of gaseous carbon dioxide to the feed water, b) providing an aqueous slurry comprising 2 to 40 wt.-% of micronized calcium carbonate based on the total weight of the slurry, wherein the micronized calcium carbonate has a particle size from 0.5 to 15 μm, and a HCl insoluble content from 0.02 to 2.5 wt.-% based on the total weight of the micronized calcium carbonate, and c) combining the feed water of step a) and the aqueous slurry of step b) in order to obtain remineralized water.
