摘　　要：采用2.75L 实验室中槽和60L 扩大槽规模,从 MnCl_2-NH_4Cl-H_2SeO_3体系制备电解锰.其中扩大槽试验稳定槽压为3.60-3.65V,电流效率87.25#,与 MnSO_4体系比较可节省电耗50-55%.阳极产生少量 Cl_2,仅占阳极产物理论总量的0.768%,达到国标 GBJ4-73要求.For preparing electrolytic manganese from MnCl_2-NH_4Cl-H_2SeO_3 system in a laboratory,the authors made use of a medium(2. 75L)electrolysing cell and a large(60L) one.With a large cell,a lower cell voltage(3. 60—3. 65V)and a higher current efficiency (87. 25%)can be obtained;and the power consumption can be reduced by 50—55% as compared with that from MnSO_4 system,The small amount of chlorine formed at the anode equals to 0.768%of total anodic products estimated theoretically.
