This process and parameters of fabricating light calcium carbonate from limestone were discussed in the paper. Raw limestone in experiment comes from Luquan city, Hebei province. The results of chemistry and XRD analysis indicate that ingredient of this limestone is mainly calcium carbonate, dolomite, silicon dioxide, which takes 83.81%, 11.03% and 1.67% separately, and a few of other impurities.

MoreA process for the production of precipitated calcium carbonate. A slurry of calcium hydroxide is agitated in a pressurized reactor, and carbon dioxide is provided under pressure to the reactor to produce precipitated calcium carbonate at a high reaction rate. Carbon dioxide is utilized at a high efficiency. Solubilized calcium ions and carbonate ions react to produce a calcium carbonate ...

2012-6-1 Highlights An alternative production process for precipitated calcium carbonate is studied. Calcium is extracted selectively from steel converter slag with aqueous solvents. Process kinetics being estimated, slag particle size is of high importance. Levels of Ca 2+, CO 3 2-and NH 3 / NH 4 + are key parameters in CaCO 3 precipitation. Regarding process chemistry, the system can also be operated ...
