摘要： PROBLEM TO BE SOLVED: To provide a method for extracting copper with a solvent, capable of preventing mixing of molybdenum accompanying copper into an organic solvent from being suppressed when copper is extracted with a solvent from a leachate leaching copper sulfide ores.SOLUTION: In a method for extracting copper with a solvent, copper is extracted with a solvent from a leachate obtained by leaching copper sulfide ores using a sulfuric acid. An organic solvent used for the extraction of the leachate contains an acidic extracting agent containing an aldoxime, and extraction is performed so that copper concentration in the organic solvent having treated after the extraction is equal to or more than predetermined concentration, and the organic solvent having treated is back-extracted. Since the leachate is leached by the organic solvent containing the acidic extracting agent containing an aldoxime, crowding of molybdenum by copper can be produced when the extraction is performed so that the copper concentration in the organic solvent having treated after extraction exceeds the predetermined value. Since the molybdenum concentration in the organic solvent having treated can be reduced, occurrence of the extraction impediment of copper resulting from molybdenum can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a method for separating and recovering copper from a copper-containing iron sulfide which contains copper and iron, by which the amount of sulfuric acid consumed in the whole steps from leaching to electrowinning is reduced, and the use of a neutralizing agent in extraction and back extraction steps is eliminated, thus allowing substantial cost reduction.
SOLUTION: The method includes the steps of: leaching a copper-containing iron sulfide with a sulfuric acid solution; mixing the leaching solution with an organic extractant to extract copper; back-extracting copper from the resulting organic extractant containing copper; and electrowinning copper from a solution after back extraction. The temperature in the leaching step is maintained in the range of 102 to 112°C. An aldoxime extractant essentially comprising 5-alkyl salicylaldoxime and containing less than 5 wt.% of alcohols or phenols is used as the organic extractant in the extraction step.
