| Abstract: | For high-arsenic fine-disseminated refractory gold ores, chemical preoxidation-cyaniding and bacterial preoxidation-cyaniding experiments were carried out. The results show that gold ores can be effectively oxidized through bacterial proxidation-cyaniding. The gold ore was preoxidated for 7d below 45 ℃ when the inoculation amount of bacterial was 10% and pulp density was 15%, the leaching rate of gold can reach 89.24%. |

| Keywords: | refractory gold ores bacterial preoxidation cyaniding gold |
