    The crusher feeds, via an apron feeder, a coarse ore stockpile that has a 91,800 t live capacity. In turn, five apron feeders reclaim ore from the coarse ore stockpile to two semi-autogenous grind (SAG) mills operating in closed circuit with pebble crusher. Each SAG mill operates with two ball mills.

  • Fine Ore Storage Bin and Stock Pile

    The trajectory of the ore as it leaves the conveyor belt will determine where in the bin or pile each size of the crushed ore will land. Once in the bin, another stage of classification takes place. The smaller ore due to its lesser size and weight, tends to filter downwards faster than the coarse material does.
