Method for removal of copper ions from copper-containing nickel chloride solution, and process for production of electrolytic nickel |
| abstract |
Disclosed are: a method for removing copper ions from a copper-containing nickel chloride solution, which can remove copper contained in the copper-containing nickel chloride solution with high efficiency; and a process for producing an electrolytic nickel. Specifically disclosed is a copper ion removal method for removing copper ions from a copper-containing nickel chloride solution (11') that is produced by the chlorine exudation of a nickel sulfide (10), which comprises: a first step of adding the nickel sulfide (10) to the copper-containing nickel chloride solution (11') containing bivalent copper ions to reduce at least the bivalent copper ions into monovalent nickel ions; and a second step of adding a nickel mat (12) and a chlorine exudation residue (13) to a slurry produced through the first step to immobilize the monovalent copper ions contained in the slurry in the form of sulfides. |
