      High grade cobalt-bearing copper-cobalt ores from Congo DRC were column leached in laboratory. The results show that high leaching rate of copper can be obtained under different column leaching conditions. Application of reductant and its adding method during spraying has significantly effect on cobalt leaching rate.
