US4018877A - Production of calcium carbonate - Google Patents

Calcium carbonate is manufactured by the carbonation of an aqueous suspension of calcium hydroxide in the presence of a complex-forming agent for calcium ions which is added subsequently to the primary nucleation stage, and preferably during a first carbonation stage. Optionally there is also added a long-chain fatty acid or long-chain fatty acid salt, preferably after a final carbonation stage.

Calcium Carbonate Production and Contribution to Coastal ...

Calcium carbonate production in coastal environments. Biological production of calcium carbonate in the oceans is an important process. Although carbonate is produced in the open ocean (pelagic, see Chapter 5), this chapter concentrates on production in coastal waters (neritic) because this contributes sediment to the coast through skeletal breakdown producing sand and gravel deposits on ...

Production of precipitated calcium carbonate from calcium ...

The current precipitated calcium carbonate (PCC) production uses mined, crushed calcium carbonate as raw materials. If calcium silicates were used instead, carbon dioxide emissions from the calcination of carbonates would be eliminated. In Finland, there could, thus, be a potential for eliminating 200 kt of carbon dioxide emissions per year, considering only the PCC used in the pulp and paper ...

Three major technological processes are used in the production of calcium carbonate fillers: milling, precipitation, and coating. However, most calcium carbonate fillers are processed by milling using a dry or wet method. Dry milling provides ultra-fine calcium carbonate grades (particle size about 0.6 μm). Natural milled calcium carbonates are added to decrease cost in rubber base adhesives ...
