Abstract

Aqs. suspension of >=25 wt. % of the mineral is formed and ground with an auxiliary grinding agent which has a particle size of 150 mu-6.35mm. and occupies a space equiv. to >=1/2 that of the suspension. Grinding is for long enough for the energy dissipated per tonne of mineral is >=250 metric hp-hrs. [FR2039650A6]
