ABSTRACT:
A process is disclosed for producing pure cobalt metal powder. The process involves contacting a cobaltous salt with a sufficient amount of an alkaline earth halide in an aqueous solution at a sufficient temperature for a sufficient time to form a solution which is essentially cobaltous halide and a solid which consists essentially of a salt of the alkaline earth and the anion of the cobaltous salt. The cobaltous halide solution is removed from the solid and the ions in the solution are complexed with ammonia in the presence of a catalyst to form a cobaltic hexammine ion. The resulting solution is treated with an acid in the presence of halide ions to form a cobaltic hexammine halide precipitate which is removed from the resulting mother liquor and dissolved in an aqueous solution to form a relatively pure solution which is treated with a sufficient amount of a metallic hydroxide to form a cobalt containing precipitate which is reduced to cobalt metal.
