metal ores (<1% copper, <1g/ton gold, < % nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.

Heap leaching has also gained increased attention as a result of its demonstrated success in being combined with the SXEW process, most notably in the copper industry. Solvent extraction – electrowinning is a hydrometallurgical combination of steps that uses reagents to extract the target metal from the solution that is obtained through leaching, and then electrowin that metal in pure form.
