Precipitated Calcium Carbonate (PCC) Manufacturing Process

Precipitated Calcium Carbonate Production. The fineness of the grain, as well as the crystal form (aragonite, calcite), is controlled by temperature, concentration of reactants and time. Depending on the chemical composition of the milk of lime used and on the purifying stages during production, both technical as well as foodstuff and pharmaceutical grades can be produced.

Calcium Carbonate

Calcium Carbonate. A completed sedimentation process results in the formation of limestone. If the sedimentation process takes place in water containing magnesium, dolomitization may occur. Part of the calcium ions in the crystal lattice are replaced by magnesium ions, leading to the formation of dolomite (CaMg(CO 3) 2 ).
