Copper

Concentrator through smelter to cathode, on both the pyrometallurgical and hydrometallurgical routes.

Concentrator

  • Crushing, grinding and classification
  • Rougher, cleaner and scavenger flotation
  • Concentrate thickening, filtration and handling
  • Tailings thickening, disposal and water recovery

Smelting and refining

  • Flash and bath smelting, matte handling
  • Converting and anode furnace operation
  • Anode casting, electrorefining and cathode handling
  • Slag cleaning and by-product recovery

Hydrometallurgical route

  • Heap and dump leaching
  • Solvent extraction (SX)
  • Electrowinning (EW) and cathode stripping
