| Abstract: | Copper was selectively recovered from crude nickel sulphate solution by using sodium thiosulfate as a precipitator. Effects of initial acidity, concentration of sodium thiosulfate, reaction temperature and time on selective recovery of copper were investigated. Results show that the reaction with an excess coefficient of 3.0 for sodium thiosulfate, an initial acidity of solution at 0.3 mol/L, at a temperature of 85 ℃ for 2 h, resulted in the precipitation rate of copper up to 99.97% with nickel loss rate only at 0.78%. |
