ABSTRACT:
A method is disclosed for producing fine cobalt metal powder which comprises adding to a solution of cobaltous chloride, sodium hydroxide in an amount equal to at least the stoichiometric amount required to form a precipitate of the major portion of the cobalt as cobaltous hydroxide and a mother liquor containing the balance of the starting cobalt, separating the precipitate from the mother liquor, water washing the precipitate to remove essentially all of the sodium therefrom, and reducing the precipitate to fine cobalt metal powder having an FSSS of from about 0.5 to about 2.0. Drying of the precipitate before reduction results in the fine cobalt metal powder having essentially no tailings.
