PRODUCTION OF PRECIPITATED CALCIUM CARBONATE
The present invention relates to the use of a depolymerized carboxylated cellulose solution for preparing an aqueous Precipitated Calcium Carbonate (PCC) slurry by slaking a material containing calcium oxide in water, followed by carbonation of the milk of lime thus obtained. The depolymerized carboxylated cellulose solution has a solid content of 25 wt. % to 40 wt. %, based on the total weight of the solution and a molecular weight of between 10 000 g/mol to 40 000 g/mol.
