Pre feasibility study in hydrometallurgical treatment of low-grade

For example, for an ore grade of 0.25%, the total energy consumption for RoM heap leach, SX and EW is about 45 MJ/kg of copper. However, the conventional smelting process consumes about 110 MJ/kg Cu. The heap leaching energy consumption was shown to be about 10 MJ/kg higher than RoM treatment.
