METHOD FOR RECOVERING COPPER FROM COPPER ELECTROLYTIC WASTE LIQUID |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for easily recovering copper from a copper electrolytic waste liquid inexpensively. <P>SOLUTION: In this method for recovering copper from the copper electrolytic waste liquid by a hydrometallurgical method for performing electrowinning from an acidic leaching liquid containing copper to be obtained by adding a mineral acid to a copper sulfide mineral to recover the copper, an alkali, e.g. calcium carbonate is added to the electrolytic waste liquid containing zinc and copper obtained after performing the electrowinning of copper, pH is maintained in a range of 4.2-4.4, and solid-liquid separation is performed to obtain precipitates containing copper. <P>COPYRIGHT: (C)2012,JPO&INPIT |
