Extraction of copper from an ammoniacal copper solution |
摘要 |
Copper can be extracted from an ammoniacal copper solution by contacting said solution with an organic phase containing a first extraction reagent consisting of a beta-diketone as well as a second extraction reagent consisting of a hydroxy oxime, a hydroxy quinoline, or an alkylaryl sulphonamido quinoline. Alternatively, the copper solution can first be contacted with an organic phase containing the first extraction agent, and subsequently be contacted with an organic phase containing the second extraction reagent. It is possible to reach a low percentage of copper in the aqueous solution by using a low number of extraction steps.
