摘要
澳大利亚犹安密矿应用中温嗜热菌氧化高砷、高硫金精矿 ,每日处理 12 0t精矿的生产厂已从 1994年运行至今。生产运行主要指标 :砷氧化率 90 %~ 95% ,黄铁矿氧化率 2 5%~ 30 % ,总硫氧化率 32 % ,金氰化率 97%
The mesothermophilic bacteria has been used in Youanmi Mine of Australia to oxide the high arsenopyrite and pyrite containing gold concentrate.A plant treating 120t/d of concentrate has been operated since 1994,and results arsenic oxidation 90~95%,pyrite 25~30%,total sulphur 32% and gold cyanidation 97%.
