Abstract
1. Process for the manufacture of mineral fillers, especially natural calcium carbonates, by wet grinding, whereby 70-80% or more of the particles are < 1 mu m but a maximum of 15% of the particles are < 0.2 mu m, characterised in that the grinding is carried out without dispersant and at a solids concentration of less than 60% by weight, in that the ground suspension is filtered and the resulting filter cake which contains about 20% water is either dried or, by the addition of a dispersant, converted to a suspension of lower viscosity.
