Liquid/liquid extraction process for copper from an aqueous sulphuric acid solution acting on the concentrated mineral or semi-finished product to be treated. The extraction is carried out in an organic solvent containing in solution an extraction agent derived from 2-phenyl-4-acyl-(3H)-pyrazol-3-ones, with the phenyl group substituted or unsubstituted. Application to the upgrading of minerals.
