Abstract: In this paper,the research on gold extraction from arsenic gold concentrate by catalytic pressure oxidation-cyanidation process was conducted,and the influence of sodium nitrite dosage,oxidation temperature,sulfuric acid dosage and oxygen partial pressure on catalytic pressure oxidation performance was investigated.The results show that with optimal conditions:sodium nitrite 50 kg/t,sulfuric acid 135 kg/t,oxidation temperature 200 ℃,oxygen partial pressure 0.6 MPa and oxidation time 2.0 h,the gold leaching rate is 97.65 %.However,the dissolution rate of gold in the process of catalytic pressure oxidation is 24.25 %.Activated carbon was used to adsorb the acid oxidation solution,and the gold adsorption rate reached 99.51 %.This process can effectively treat arsenic  gold concentrate,with good indexes.
