Recovery of copper from cupronickel alloy scraps was carried out with direct low current density electrolysis method. The effects of electrolyte temperature, current density and gelatin concentration on the cathode copper quality were examined. The results show that the diffusion rate of copper ion can be accelerated while the electrolyte temperature rises in a certain range, which will ease the lacking degree of copper ion on the surface of cathode and fine the crystallization of cathode copper, though the cathode over-potential deceases. When the Cu2+ and H2SO4 concentrations are of 45 g/L and 180 g/L, the current density of 100 A/m2 is less than 0.1 times of limiting current density in 48 h, the electrolysis process is in Tafel area, smooth cathode copper product can be obtained. Under the conditions of electrolyte temperature 60℃, cathode current density 100 A/m2 and gelatin concentration 40 mg/L, the purity of copper cathode of 99.98% can be obtained, while the residual anode rate is 17%~19% and copper recovery rate 98.6%.
