含氰尾矿作为充填骨料进行井下充填可有效解决其尾矿库堆存导致的环保问题，提高固体废物资源利用率，降低充填成本，具有良好的经济效益和环境效益。采用过氧化氢氧化法和过碳酸钠氧化法对某黄金矿山含氰尾矿浆进行无害化处理，并对药剂和试验条件进行了优化。结果表明：过氧化氢氧化法、过碳酸钠氧化法处理后的含氰尾矿浆毒性浸出液中的易释放氰化物及主要重金属含量均低于HJ 943—2018《黄金行业氰渣污染控制技术规范》中氰渣回填要求。综合考虑药剂成本、储存、运输、使用条件等，推荐使用过碳酸钠氧化法。研究可为黄金行业含氰尾矿作为充填骨料的无害化处理提供参考。

Utilizing cyanide⁃containing tailings as filling aggregate for underground filling can effectively addressenvironmental issues caused by tailings pond storage, improve the utilization rate of solid waste resources, and reducefilling costs, demonstrating significant economic and environmental benefits. In this study, cyanide⁃containing tailingsslurry from a gold mine was treated using hydrogen peroxide oxidation and sodium percarbonate oxidation methods,with reagents and experimental conditions optimized. Results show that the easily released cyanide and main heavymetal contents in the toxic leachate of the treated tailings slurry are lower than the requirements for cyanide residuebackfilling specified in HJ 943-2018 technical specification for pollution control of cyanide leaching residue in goldindustry. After considering factors such as reagent cost, storage, transportation, and usage conditions, the sodium percar⁃bonate oxidation method is recommended. This study provides a reference for the detoxification treatment of cyanide⁃containing tailings as filling aggregate in the gold industry.
