PROCESS FOR DIRECT ELECTROCHEMICAL RECOVERY OF COPPER FROM DILUTE ACIDIC SOLUTIONS Abstract of the Disclosure The invention relates to the direct electrochemical recovery of copper from dilute acidic solutions of pregnant or copper bearing liquor from copper leaching systems. The pH of the liquor is maintained below 2.2. The liquor is introduced into an electrolytic cell having a cathode of an electrically conductive porous material and an anode. A current of 3 to 100 amps per square foot of cross-section is applied to the cathode and the liquor is flowed through the cell at such a rate that virtually all the copper in the liquor is collected at the cathode. The copper is then recovered from the cathodic material. This method allows the utilization of a recovered barren (decopperized) leach solution in a recycling process for recovering copper from sources such as mine waste dumps or in-situ mined copper.
