This paper puts forward the Theory of Oxidant supplying Oxygen which better explains the leaching mechanism. This theory absorbs and denies the five theories brought up about gold leaching mechanism with cyanide, analyses and caculates from them odynamics and kinetics respectively. These give reliable theorial basis for further catching the mechanism and essence of cyaniding and non cyaniding ways.
