Abstract: Most gold ores with high sulfur content and  rich   in arsenic are wrapped by minerals containing arsenic and sulfur,so that cyanide leaching is difficult and oxidation pretreatment is necessary.Common pretreatment methods include biological oxidation,roasting oxidation,pressure oxidation,ultrasonic oxidation and chemical oxidation.This paper introduces the development history and basic mechanism of these methods,and analyzes their advantages and disadvantages as well as the applicability,providing references for future researchers on related research.
