Abstract：In order to increase the leaching rate of antimony from antimony-bearing gold ore and reduce the influence of antimony content in ore after antimony removal process on two-stage roasting, an experimental study was conducted on alkaline leaching of antimony from the antimony flotation tailings with sodium sulfide. The results showed that the antimony leaching rate reached 95.34% after leaching for 15 min at 72 ℃, with 60 g/L of sodium hydroxide and 160 g/L of sodium sulfide, as well as a liquid-solid ratio at 3∶1. On this basis, the antimony leaching rate, purity and output of cathode antimony have been obviously improved after technological transformation in terms of antimony leaching feeding mode, filter press with washing, replenishment and additive feeding mode for precious antimony-containing liquid in electrowinning, indicating that better economic benefits have been attained.
