ABSTRACT HYDROMETALLURGICAL TREATMENT OF COPPER-BEARING HEMATITE RESIDUE A method is provided for recovering copper values from a copper-bearing hematite residue in a single stage. It comprises leaching the residue in an aqueous sulphuric acid solution in the presence of ammonium, sodium or potassium ions, at a temperature between about 80°C and the boiling point of the solution so that copper values are dis- solved while iron is precipitated as jarosite. The method is particularly suitable for the treatment of residues re- sulting from an oxidizing pressure leach of copper concentrates.
