Fig. 14 shows the screening equipment for a copper ore processing plant operated by Vale in the Solobo mine, which processes 24 Mta of copper ore annually. A crucial feature of this plant is that the secondary crushing is performed by high-pressure roller presses (HPGRs), which already produce a high proportion of fines.
