Title:
METHOD FOR PRODUCING Co-CONTAINING SOLUTION
Document Type and Number:
Japanese Patent JP2012001750
Kind Code:
A
Abstract:
To provide a method for producing a Co-containing solution effectively separating and removing Ni from a CoNi material solution high in an Ni amount, and further selectively recovering Co.
In this method for producing a Co-containing solution, a reducing agent and CoS are added in a solution containing Ni and Co (called "a CoNi material solution") to adjust oxidation-reduction potential (reference electrode: silver-saturated silver chloride electrode) of the CoNi material solution to -550 to -400 mV to precipitate and remove the Ni element in the solution as a sulfide, and the Co-containing solution containing the Co element in an ionized state is obtained.
