Selective removal of antimony from refractory gold ores by ...

01/12/2019  The antimony in refractory gold ores was selectively removed by ultrasound with alkaline sodium sulfide. The removal rate of antimony reaches 94.50% under the optimum conditions: the ultrasonic power is 1500 W, the Na 2 S concentration is 2 mol/L, temperature is 55 °C and time is 60 min and the NaOH concentration is 1 mol/L. Ultrasound enhances the removal efficiency of antimony

Refractory gold ores are generally defined as those ores that do not give economical recoveries in conventional cyanide circuits where the ore has been ground to around 53 to 75 microns. There are several reasons as to why an ore may be refractory. The two most common are: - 2 1) The gold is locked in refractory sulphide minerals such as pyrite, arsenopyrite or pyrrhotite and occurs in both ...
