  • Constraints Of Grinding Mill To The Environment

    The original flowsheet involved grinding in two AG mills and a secondary pebble mill, sequential copper flotation and then nickel flotation in order to produce two separate concentrates. However, about 12 per cent of the copper was not recovered during the copper flotation stage because of poor liberation and grade-recovery constraints.
