Fine wastes comprising at least one material containing calcium carbonate, the fine wastes a) have a solids content of 78.0% by weight to 90.0% by weight, based on the total weight of the fine wastes , b) comprising particles of at least one material containing calcium carbonate having an i) particle size by weight d75 of 0.7 to 3.0 µm, ii) a median diameter of particle size by weight d50 from 0.5 to 2.0 μm, iii) a particle size by weight d25 of 0.1 to 1.0 μm, measured according to the sedimentation method, and c) comprising particles of at least one carbonate-containing material of calcium that have a specific BET surface area of 4.0 to 12.0 m2 / g, measured by adsorption of nitrogen gas using the BET isotherm (ISO 9277: 2010). |
