Abstract:
A method is provided for effecting the dissolution of a cobaltic hydroxide-containing precipitate which may also contain nickel, wherein an aqueous slurry of the precipitate containing trivalent metal is acidified to a pH of from about 0. 1 to 2, and the aqueous slurry then treated with an organic reductant to effect substantial reduction of the trivalent metal to the divalent state and hence the dissolution of said precipitate.
