Mineral carbonation, a process of carbondioxide (CO 2) captured from the atmosphere or flue gases, is a way to sequestrate CO 2 safely and permanently. In this technology, CO 2 is chemically reacted with calcium, magnesium, sodium, and ironcontaining materials. The procedure is analogous to natural weathering processes, to form thermodynamically stable and environmentally harmless carbonate ...

The Calcium Carbonate Manufacturing Process. Natural mineral sources are necessary to make commercially usable calcium carbonate. Manufacturing processes are used to improve specific properties and reduce the size of particles within the material. Calcium carbonate is mined from open pits or underground, then drilled, blasted, and crushed.

The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media. For example, in 10 hours of milling, specific surfaces of 40 and 25 m 2 /g were obtained for alumina and barite, corresponding to 38 and 56 nm equivalent spherical diameter, respectively.
