    A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching ofphase, copper recovery increases as well, and copper oxide minerals were completely leached out Besides copper ions, considerably high ferrous/ferric ion concentrations were achieved in the leach solution This concentration was sufficiently high for the use of either solvent extraction or ion exchange techniques or both for further treatment ofLEACHING OF LOWGRADE COPPER ORES: A CASE STUDY FOR
