grinding of mine tailings

  • Dams and tailings management Newcrest

    Tailings are the resulting material from finely-ground processed ores that have been through a number of sizing grinding and processing steps. Tailings are generally discharged as dense slurry into containment areas a tailings storage facility (TSF) or through deep sea tailings placement (DSTP) in suitable deep-ocean locations.
