Separation of cobalt from nickel by ozonation in the presence of ammonium salts

A method is provided for separating cobalt from a nickel solution containing cobalt in the cobaltous state and an ammonium salt comprising subjecting said solution containing at least 0.2 grams per liter of ammonium ion to ozonation while maintaining the pH thereof from about 4.5 to 6, until said co...

Zusammenfassung:A method is provided for separating cobalt from a nickel solution containing cobalt in the cobaltous state and an ammonium salt comprising subjecting said solution containing at least 0.2 grams per liter of ammonium ion to ozonation while maintaining the pH thereof from about 4.5 to 6, until said cobalt has been oxidized to the cobaltic state and simultaneously precipitating said cobalt in the cobaltic state at a temperature ranging from about 10 DEG to 90 DEG C.
