Process for making copper foil |
| abstract |
The present invention relates to a process for making copper foil from copper-bearing material comprising: (A) contacting said copper-bearing material (10) with an effective amount of d least one aqueous leaching solution (40); (B) contacting a copper-rich aqueous leaching solution (11) with an effective amount of at least one water-insoluble extractant (20); (C) separating a copper-rich extractant (48) from a copper-depleted aqueous leaching solution (14); (D) contacting said copper-rich extractant (48) with an effective amount of at least one stripping solution (22); (E) separating a copper-rich stripping solution (16) from a copper-depleted extractant (64); (F) flowing said copper-rich stripping solution (25) between an anode (28) and a rotating cathode (26), and applying an effective amount of voltage across said anode and said cathode to deposit copper (26a) on said cathode; and (G) continuously removing copper foil (12) from said cathode. |
