Study on Improving Gold Cyanidation Recovery of an Arsenic-antimony-bearing Gold Concentrates

Guang Yang

Abstract

The experimental study were carried out to improve the gold cyanidation recovery of an arsenic-antimony-bearing gold concentrates.Some programs were researched to optimize experimental conditions,such as direct cyanidation,bio-oxidation and cyanidation,roasting oxidation and cyanidation.Under the optimal conditions of process and control,the gold cyanidation recovery reached 93.78%.
