摘要： Provided is a method for separating copper from nickel and cobalt, which can efficiently and selectively separate copper from nickel and cobalt in a substance containing copper, nickel, and cobalt in a waste lithium ion battery, etc. In this method for separating copper from nickel and cobalt, a substance containing copper, nickel, and cobalt is sulfurated to obtain a sulfide, the obtained sulfide that contains copper, nickel, and cobalt is brought into contact with an acid solution to obtain a solid containing copper and a leachate containing nickel and cobalt. Here, the sulfide preferably contains copper sulfide as a main component, and contains nickel metal and cobalt metal. In addition, when bringing the sulfide into contact with the acid solution, the added amounts of the sulfide and the acid solution are preferably adjusted such that the oxidation-reduction potential of the obtained leachate is maintained at 150 mV or less where a silver/silver chloride electrode is a reference electrode.

摘要： Provided is a method for efficiently separating copper from nickel and cobalt from a sulfide containing nickel and cobalt together with copper. The present invention is a method for separating copper from nickel and cobalt, the method comprising pulverizing a sulfide containing copper and nickel and cobalt into a predetermined size and then stirring the resultant product under the condition having an oxidation-reduction potential (a reference electrode: a silver/silver chloride electrode) of less than 100 mV using an acid solution to perform a leaching treatment. In this separation method, a leach liquor in which nickel and cobalt are leached and a leach residue containing copper sulfate are produced as the result of the leaching treatment.

摘要： Provided is a method for producing solutions, by which two solutions, namely a high-purity nickel sulfate solution and a mixed solution of nickel sulfate and cobalt sulfate are able to be obtained at the same time from a sulfuric acid solution containing nickel, cobalt and calcium. A method for producing solutions according to the present invention uses a sulfuric acid solution containing nickel, cobalt and calcium and performs a first step S1 for producing a mixed solution of nickel sulfate and cobalt sulfate from the sulfuric acid solution and a second step S2 for producing a solution of nickel sulfate from the sulfuric acid solution in parallel. In the first step, the sulfuric acid solution is subjected to solvent extraction by means of an extractant, thereby obtaining a first organic solvent after extraction containing calcium and a first extraction residue containing nickel and cobalt. In the second step, the sulfuric acid solution is subjected to solvent extraction by means of an extractant, thereby obtaining a second organic solvent after extraction containing cobalt and calcium and a second extraction residue containing nickel.
