摘　　要：在CoCl2体系中,采用密闭电解槽为电解设备,进行无隔膜、永久阴极电积钴试验。结果表明,该工艺避免了氯气泄漏,改善现场作业环境,在电流密度为500A/m2时,吨钴直流电耗为3 400kWh。A permanent electrowinning process without membranes was adopted to prepare electrical cobalt from COC12 system in closed electrolytic cells. The results show that leakage of chlorine gas is avoided and the operation conditions are improved. The energy consumption for one ton cobalt is 3 400 kWh with current density of 500 A/m2
