Abstract
Metal sulfide powder coated with copper is produced by mixing powder of a metal and/or an alloy baser than copper with powder of a metal sulfide, and then adding an acidic solution containing copper ions to the resulting mixture with stirring. The metal sulfide particles are coated with metallic copper that results from a cementation reaction. Where the metal sulfide powder contains too coarse or fine particles, it is ground, granulated, and sized before the mixing.
