  • Upgrading low grade gold ore stockpiles Mineral Processing

    Ore is treated through the Phoenix mill, which is a conventional gold processing plant (primary crushing, SAG mill, ball mill, gravity separation and carbon in leach (CIL) gold recovery) with a nameplate capacity of 720 000 t/a. Low grade stockpilesDesign of Gravity Reclaim Stockpiles Powder & Bulk,Gravity reclaim stockpiles are an effective way to store large quantities of material. Our gravity stockpile reclaim designs are engineered based on the measured flow properties of the bulk solid being handled, using proven in-house developed methods.. Each of our gravity stockpile reclaim designs is based on an expanded flow principle which incorporates mass flow hopper(s) at the stockpile base.GRADE CONTROL BLENDING AND SELECTIVITY FOR OPTIMAL ,Waste and marginal ore are also separated to different destinations. The degree of selectivity in the open-pit serves to minimise dilution and allows for blending from a range of stockpiles. A tracking database monitors ore tonnes and grades on stockpiles to enable optimal blending for the required plant process performance.
