Abstract
The invention relates to a process for wet grinding of natural and/or synthetic carbonates in wet suspensions in which the viscosity of the mass is decreased and a favorable particle size range distribution is obtained having a small portion of very fine overground particles. The carbonates in the wet grinding are mixed with zeolites to 0.05 to 3.0% by weight based on the dry weight of the carbonates. Chemical dispersants are used to help effect the process.
