Abstract
This paper introduces a new clean hydrometallurgy technology of recovery bismuth from hydrochloric BiCl 3 solution by electrodeposition .Effects of current density , solution temperature , concentration of HCl , Bi3+and NaOH parameter on diaphragm were investigated .The experiments results show that , in the optimum conditions of current density 150 A/m2, temperature 45~55℃, 3.5 mol/L HCl, 110 g/L Bi 3+and 15 g/L NaOH.NaOH could transform into NaClO 3 through re-action in anode , bismuth could be obtained in cathode , current efficiency could reach a maximum of 98 .82 %, and the purity of cathodes bismuth was 99 .8%.The electric fluid of anode and cath-ode could be recycled , and which achieves closed circulation of materials .关键词
