The method for manufacturing high purity nickel sulfate and a method for removing impurities from the nickel-containing solution

The present invention provides a method for removing impurities from elemental magnesium nickel-containing solution is selectively removed, as well as the method for removing impurities using a method for producing obtain a high purity nickel sulfate. Method for manufacturing high purity nickel sulfate, wherein the self-contained manufacturing process of a manufacturing method of a nickel solution to generate a high purity nickel sulfate, the nickel-containing solution in a manufacturing process embodiment comprises a step of an impurity element removing treatment step of: adding an alkali hydroxide to the nickel-containing solution is formed in the manufacturing process step hydroxide hydroxide slurry, adding an alkaline carbonate to the hydroxide slurry was carbonated to form a slurry and recovered from a solution of nickel carbonate chemical ingredients sequence, obtained by solid-liquid separation step of the slurry, and the neutralization step and the recovering processing of an impurity element contained in the nickel-containing solution in the manufacturing process of the solid-liquid separation of the reaction solution obtained in.
