Improved Copper/Iron Selectivity in Solvent Extraction

Copper ore bodies are typically composed of three distinct zones (Figure 1). Weathering and oxidation convert the copper in the top layers of the orebody to copper oxide minerals, and this represents approximately 10 % of the total copper. A transition from the oxide layer to the supergene area leads
