中文摘要: 分别采用硝酸和生物浸出对废旧手机电路板颗粒样品进行预处理,然后在硫脲浓度12 g/L、Fe2(SO4)3质量分数0.3%、溶液pH=1.5、30 ℃条件下进行提金试验,从金浸出率、金属杂质浸出率和环境影响等方面对这两种预处理工艺进行评估。结果表明,硝酸氧化预处理—硫脲提金工艺在金属除杂效率方面有较大优势;而生物浸出—硫脲提金工艺的优势主要体现在生产成本和环境影响等方面。
Abstract:Waste mobile phone circuit boards were pretreated by nitric acid oxidation and bioleaching respectively. Gold was extracted from pretreated samples in thiourea system, in which thiourea concentration is 12 g/L, Fe2(SO4)3 mass fraction is 0.3%, pH value of solution is 1.5, and temperature is 30 ℃. Gold leaching rate, metal impurities removal rate, and environmental impact were taken into consideration to evaluate two pretreatment processes. The results show that nitric oxide pretreatment has more advantages in terms of metal cleaning efficiency while bioleaching pretreatment outperforms in production cost and environmental impact.
