Abstract: The solvent extraction process for removal of bismuth and antin'iony from copper electrolyteby primary amine N1923-additive(iso-octanol)-kerosene has been studied.The extraction e-quilibrium models are created on the basis of experimental equilibrium data.An obJective func-tion for optimization is created which can satisfy different demands.A variety of optimized tech-nological parameters combination of the process are determined and one of thern was veified withlaboratory extraction cascade experiments.It indicates lhat the experimental values arc nearlyconsistent with the calculated values.
