CALCIUM CARBONATE

SECTION VII. BROAD OUTLINE OF MANUFACTURING PROCESS. Precipitated calcium carbonate is manufactured by calcining line and recarbonating the hydrated slaked lime in vertical carbonation towers. The reaction is exothermic and proper temperature control is maintained to get desired quality of the product.

Precipitated Calcium Carbonate (PCC) - Minerals Technologies Inc.

While the process is simple on a laboratory scale, making precipitated calcium carbonates commercially on a large scale requires a great deal of process control and process technology to assure the right size, uniformity, shape, surface area and surface chemistry. This body of PCC technology developed by Specialty.

Calcium carbonate - Wikipedia

Fine ground calcium carbonate (GCC) is an essential ingredient in the microporous film used in diapers and some building films as the pores are nucleated around the calcium carbonate particles during the manufacture of the film by biaxial stretching. GCC or PCC is used as a filler in paper because they are cheaper than.
