Abstract

THE PRESENT INVENTION RELATES TO A PROCESS FOR MAKING COPPER FOIL FROM COPPER-BEARING MATERIAL COMPRISING:(A)CONTACTING SAID COPPER-BEARING MATERIAL WITH AN EFFECTIVE AMOUNT OF AT LEAST ONE AQUEOUS LEACHING SOLUTION TO DISSOLVE COPPER IONS INTO SAID LEACHING SOLUTION AND FORM A COPPER-RICH AQUEOUS LEACHING SOLUTION;(B)CONTACTING SAID COPPER-RICH AQUEOUS LEACHING SOLUTION WITH AN EFFECTIVE AMOUNT OF AT LEAST ONE WATER-INSOLUBLE EXTRACTANT TO TRANSFER COPPER IONS FROM SAID COPPER-RICH AQUEOUS LEACHING SOLUTION TO SAID EXTRACTANT TO FORM A COPPER-RICH EXTRACTANT AND A COPPER-DEPLETED AQUEOUS LEACHING SOLUTION ;(C)SEPARATING SAID COPPER-RICH EXTRACTANT FROM SAID COPPER-DEPLETED AQUEOUS LEACHING SOLUTION;(D)CONTACTING SAID COPPER-RICH EXTRACTANT WITH AN EFFECTIVE AMOUNT OF AT LEAST ONE AQUEOUS STRIPPING SOLUTION TO TRANSFER COPPER IONS FROM SAID EXTRACTANT TO SAID STRIPPING SOLUTION TO FORM A COPPER-RICH STRIPPING SOLUTION AND A COPPER-DEPLETED EXTRACTANT;(E)SEPARATING SAID COPPER-RICH STRIPPING SOLUTION FROM SAID COPPER-DEPLETED EXTRACTANT;(F)FLOWING SAID COPPER-RICH STRIPPING SOLUTION BETWEEN AN ANODE AND A ROTATING CATHODE, AND APPLYING AN EFFECTIVE AMOUNT OF VOLTAGE ACROSS SAID ANODE AND SAID CATHODE TO DEPOSIT COPPER ON SAID CATHODE; AND(G) CONTINUOUSLY REMOVING COPPER FOIL FROM SAID CATHODE.
