ABSTRACT:
Fine particle size cobalt metal powder is prepared absent tailings by heating an aqueous solution of soluble cobaltic ammine halide to a temperature of at least about 120 degrees centigrade for a sufficient period of time to decompose said cobaltic ammine halide and form a cobalt containing precipitate. The precipitate is separated from the solution and reduced in a reducing atmosphere to produce fine metal cobalt powder.
