NICKEL-COBALT SEPARATION

A method is provided for enriching nickel in a nickel-cobalt solution to a nickel-to-cobalt ratio of over 2000:1, wherein an aliquot portion of the solution is removed, the nickel precipitated from said aliquot portion in the nickelous state, the nickelous precipitate thereafter oxidized to the nick...

Zusammenfassung:	A method is provided for enriching nickel in a nickel-cobalt solution to a nickel-to-cobalt ratio of over 2000:1, wherein an aliquot portion of the solution is removed, the nickel precipitated from said aliquot portion in the nickelous state, the nickelous precipitate thereafter oxidized to the nickelic state and the oxidized nickel precipitate then mixed with the remaining nickel-cobalt solution to oxidize the cobalt therein to the cobaltic state which precipitates from the solution, thereby highly enriching the solution in nickel.
