摘　　要：针对高砷微细浸染型难处理金矿,进行了化学预氧化-氰化浸金和细菌预氧化-氰化浸金。结果表明,细菌预氧化-氰化浸金能有效氧化金矿石,在细菌接种量10%、矿浆浓度15%、45℃下预氧化7 d,金浸出率达到89.24%。For high-arsenic fine-disseminated refractory gold ores, chemical preoxidation-cyaniding and bacterial preoxi- dation-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%.
