US6251356B1 A 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 ....
Microbiologically induced calcite precipitation Microbiologically induced calcium carbonate precipitation (MICP) is a bio-geochemical process that induces calcium carbonate precipitation within the soil matrix Biomineralization in the form of calcium carbonate precipitation can be traced back to the Precambrian period Calcium carbonate can be precipitated in three polymorphic forms, which in the order of their usual stabilities are ....
Calcium carbonate The resulting calcium sulfite collects at the base of the absorber and compressed air is blown into this residue The calcium sulfite reacts with the air to form calcium sulfate (gypsum), used to make, for example, plaster board and cement Very fine and pure calcium carbonate is used as filler in ,...
US20030051841A1 A method and apparatus for the production of calcium carbonate and calcium silicate in common superatmospheric reactors Multiple reactors can be provided for switching production between reactors, and advantageously utilizing process waste heat On site production of both PCC and Calcium Silicate Hydrates is thus achieved in a paper mill...
Calcium carbonate Precipitated calcium carbonate, made by dropping calcium oxide into water, is used by itself or with additives as a white paint, known as whitewashing Calcium carbonate is added to a wide range of trade and do it yourself adhesives, sealants, and decorating fillers Ceramic tile adhesives typically contain 70% to 80% limestone...
