| Abstract: | In the report, the processing method of recovering cobalt from high-manganese-cobah ore was opti- mized. With SO2 as reductive agent in acid environment, a series of experiments was performed to obtain the op- timum processing conditions, which are as described as follows ： adding SO2 200mL/min, temperature at 60℃, ratio of liquid to solid（L/S） at 4： 1, 4h processing time, 2.0mL concentrated sulfuric acid dissolved in 400mL water. Under these conditions, the yield of cobalt attained 96.8%. |
