| Abstract: |
| Antimony in antimony-bearing gold concentrates was recovered by alkaline sodium sulphide leaching, and segregation-free electrodeposition. Based on small-scale experiment, industrial practice was carried out according to actual conditions of production site. After optimization of process parameters of electrodeposition, comprehensive leaching rate of antimony is 96.72%, purity of cathode antimony is 96.36%, antimony concentration in barren liquor is 5.54 g/L, comprehensive current efficiency is 63.84%, and NaOH consumption for one ton antimony is 617.2 kg. |
