The fine fraction serves as a feedstock for the tertiary comminution stage, which employs ball mills, while the oversize fraction is returned to the HPGRs. In the example of Vale's Solobo Mine, the material classification is performed by hydrocyclones (Fig. 15) after the tertiary milling and before feeding to the flotation stages.
