The hydrolysis rate of Co-bearing ferrous chloride at elevated temperature and the conditionsof separation of Co from Fe have been investigated. The hydrolysis process is comprised of theinterfacial chemical reaction and the intra-grain diffusion. At the stage under the control of theinterfacial chemical reaction, the apparent rate constant k equals to 198.79exp(-80.57/RT). Theeffects of the temperature, the partial pressure ratio of water vapor and the reaction time on theCo recovery and the separation of Co from Fe are examined. The optimum hydrolysis conditionsare determined.
