摘　　要：某金矿氰化尾矿浆中氰化物和砷元素超标,分别采用铁盐处理技术、因科法与铁盐联合处理技术、氯氧化法、压滤洗涤技术、双氧水氧化法对其进行无害化处理试验研究。结果表明,采用双氧水处理技术能够有效去除氰化物和砷元素,处理后的氰渣达到相关规范和标准的要求。The cyanide and arsenic in the cyanidation tailing pulp of a gold mine exceed the standard.The experimental study on the harmless treatment of cyanide tailing pulp was carried out by using the iron salt treatment technology,the joint treatment technology of Yinke method and iron salt,the chlorine oxidation method,the pressure filtration washing technology and the hydrogen peroxide oxidation method.The results show that hydrogen peroxide treatment technology can effectively remove cyanide and arsenic,and the treated cyanogen residue meets the requirements of relevant specifications and standards.
