Deposit Type

  • Porphyry


Summary:

The El Abra mine is a porphyry copper deposit that has sulfide and oxide mineralization. The predominant primary sulfide copper minerals are bornite and chalcopyrite. There is a minor amount of secondary sulfide mineralization as chalcocite. The oxide copper minerals are chrysocolla and pseudomalachite. There are lesser amounts of copper-bearing clays and tenorite.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The available fleet consists of twenty-three 242-metric ton haul trucks loaded by four shovels with buckets ranging in size from 29 to 41 cubic meters, which are capable of moving an average of 216,000 metric tons of material per day.


Crushing and Grinding


Processing

  • Heap leach
  • ROM/dump leach
  • Solvent Extraction & Electrowinning

Source: Subscription required

Summary:

The El Abra operation consists of an open-pit copper mine and a SX/EW facility with a capacity of 500 million pounds of copper cathode per year from a 125,000 metric ton-per-day crushed leach circuit and a similar-sized ROM leaching operation.
