ep1738750a1 - method of granulating calcium carbonate and

A method of granulating calcium carbonate is provided. Such a method entails the inclusion of very low amounts of an aqueous solution citric acid to a calcium carbonate material, with subsequent, mixing, drying, milling, and sieving to provide the correct target particle size range for the resultant granulated materials. Such granulated calcium carbonate materials exhibit very high available

us4509987a - calcium carbonate dispersions - google patents

Concentrated (e.g. above 72% by weight) dispersions of calcium carbonate ground to a particle size such that at least 87% by weight of the particles are less than 2 μm in size have a tendency to gel on standing. In the invention this tendency is minimized or eliminated by using, as dispersing agent, a copolymer of from 5 to 75% by weight AMPS and 95 to 25% by weight acrylic acid, or a water
