Integrating Bulk Ore Sorting into a Mining Operation to Maximise Profitability. Abstract. As high grade ore deposits are depleted, remaining deposits are generally lower grade and require the mining and processing of larger volumes of material per tonne of product. These low grade deposits often contain a large proportion of barren gangue.
