| titleOfInvention | Method for producing cobalt sulfate |
| abstract | PROBLEM TO BE SOLVED: To produce cobalt sulfate from an aqueous solution containing cobalt by using a solvent extraction method, in which cobalt is preferentially extracted but contains an element having a small separation coefficient, and is efficiently separated. The object is to produce a cobalt sulfate solution. SOLUTION: A method for producing cobalt sulfate from an aqueous solution containing cobalt and containing Ni, Mg, Ca, and Na elements as impurity elements. (1) 2-ethylhexylphosphonic acid mono-2-ester, which is an organic solvent of phosphonic acid An extraction step of extracting cobalt from an aqueous solution containing cobalt using di- (2,4,4-trimethylpentyl) phosphinic acid, which is an organic solvent of ethylhexyl ester or phosphinic acid, and (2) the extraction of cobalt from the phosphonic acid. An aqueous solution of cobalt sulfate is brought into contact with an organic solvent or an organic solvent of the phosphinic acid, and impurity elements Ni, Mg, Ca, and Na contained in the organic solvent of phosphonic acid or the organic solvent of phosphinic acid extracted from the cobalt, A washing step of partitioning and separating in the contacted aqueous cobalt sulfate solution, (3) the impurity element The step (1) to the step (3) of the back extraction step in which cobalt is back-extracted with sulfuric acid from the organic solvent of phosphonic acid or the organic solvent of phosphinic acid separated from each other. [Selection figure] None |
