The invention belongs to the technical field of metallurgy, and in particular, relates to a high-sulfur cobalt copper ore treatment process. The high-sulfur cobalt copper ore treatment process with low cost and high leaching rate mainly comprises such procedures as fluidized-bed roasting, low-acid leaching, flotation, high-acid leaching, high-copper extraction and low-copper extraction. The sulfation rates of cobalt and copper after fluidized-bed roasting of a high-sulfur cobalt copper ore are both higher than 85%; the leaching rates of cobalt and copper are both higher than 98%; the cobalt and copper grades of leaching slag are respectively lower than 0.15% and 0.30%; the roasting process is a self-heating process without replenishing external energy; the energy cost is low; steam generated by the ore fluidized-bed roasting can be used for heating wet leaching, fluidized-bed roasting of the high-sulfur cobalt copper ore, leaching and flotation; and other accessories are not needed besides of adding of few flotation reagents, so that the accessory cost is low, and such harmful elements as chlorine cannot be introduced to cause corrosion of equipment and degradation of a copper extracting agent.
