Abstract

Regrinding of middlings in a mineral-product dressing process of the kind in which the middlings are reground in order to crush individual half-grains and release valuable mineral therefrom, is carried out in a mill using an agitated grinding medium. The middlings are reduced to a particle size which is smaller than k80 = 100 mu m. There are used grinding bodies having a mean size of from 2 to 6 mm.
