Abstract: Recycling gold tests on some pyrite cinder were conducted, according to the result of process mineralogy of the pyrite cinder. The results indicated that the influence of Fe and Cu on cyanide leaching was eliminated by pretreatment. As a result, the leaching rate of gold increased from 52.15% to 78.92% by the process of the pretreatment and cyaniding craft. The technology provides a effective technical way for recovery of gold in the pyrite cinder.
