中文摘要: 针对某难处理金精矿含砷、高碳的特点，采用生物氧化－氰化炭浸提金工艺，考察了矿浆浓度、氧化时间、溶氧量、搅拌速度、培养基用量等因素对Fe、As、S脱除率，硫化物氧化率及金浸出率的影响。氰化炭浸试验结果表明，金的浸出率由直接氰化炭浸时的15.53%提高到95.82%，同时分析了氧化过程Eh、pH变化及Fe的行为。
Abstract:Experimental research on bacterial oxidation of refractory gold concentrates was carried out. The effects of several factors such as pulp density, oxidation time, dissolved oxygen, stirring speed and culture medium dosage on the removal rate of Fe/As/S, oxidation rate of sulfide and the extraction rate of gold were investigated. By cyaniding CIL gold extraction, the extraction rate of gold increased from 15.53% in the absence of bacterial oxidation to 95.82%. Furthermore, the Eh, pH diagrams and the behavior of Fe were also analysed.
