METHOD OF PRODUCING NICKEL SALT SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide an improved method for converting nickel into a nickel salt solution.SOLUTION: Nickel is dissolved and reacted in an oxygen-enriched acidic solution to produce a nickel salt solution as illustrated in the chemical equation, Ni+H2X+YzO2→NiX+H2O, where X is a conjugate base of a representative acid H2X.
