During heap bioleaching for copper recovery, solution containing high concentrations of copper is recycled to the heaps. The commonly used 1,10-phenanthroline assay is not suitable in such situations; the presence of 6 g L−1 copper in a solution containing 50 mg L−1 ferrous iron resulted in the complete loss of the absorbance band associated with the tris(1,10-phenanthroline)iron(II) complex.

Heap bioleaching performance is dependent on the contacting of the leach solution with the ore bed, hence on the system hydrodynamics. In this study two experimental setups were used to examine hydrodynamics associated with irrigation from a single drip emitter, one of the most common methods of heap irrigation.
