Method for producing hydroxylated nickel compounds

摘要

A method for the production of hydroxylated nickel compounds from a solution of nickelous ions. In the first stage, a solution of nickelous ions is electrolyzed while the catholyte is maintained at a pH from about 1 to 6 and at a temperature of less than about 50 DEG C. In the second stage, the precipitate obtained during the first stage is recovered. The method is applied to the production of highly pure nickel hydroxide.
