难浸含砷金精矿生物预氧化生产实践

Operation practice of preliminary biooxidation of refractory arsenical gold concentrate

介绍了国内第一个日处理 10t难浸金精矿生物预氧化—氰化炭浸提金工厂的生产工艺、技术参数、经济指标及存在问题。经过生物预氧化后 ,金精矿金回收率达到90 .78%。

This paper introduced the operation art,technical parameters,economic index and problems existed in the cyanide mill which is the first plant in the country to treat 10t refractory gold concentrate per day by way of preliminary biooxidation followed by CIL.Through preliminary biooxidation,the gold recovery rate increased to 90.78%.
