IMPROVEMENT OF HYDROMETALLURGICAL TREATMENT OF IMPURITIES CLEARED BY PYROMETALLURGICAL TREATMENT OF COPPER |
| abstract |
Impurity streams generated during the metallurgy of copper are hydrometallurgically processed at ambient pressure for recovery of primary values in an energy-efficient manner and with the capture and conversion of metallic impurities to states that are acceptable for disposal into the environment. Hallmark features of the various embodiments of this invention include the water leach of flue dust, a controlled acid leach stage in which metal species are solubilized, the extraction of copper as a sulfide, and the ability to operate the various process stages at essentially ambient pressure. |
