摘　　要：随着易处理和高品位金矿资源的逐渐枯竭,难处理金矿已成为黄金行业的主要生产来源。难处理金矿中的金通常以微细粒形式存在,与硫化物、碳质物等杂质形成复杂的化合物或包裹体,导致常规氰化浸出法难以有效提取金。为了提高金的浸出率,预处理技术成为关键。系统综述了难处理金矿的预处理技术研究现状,重点介绍了热压氧化法、焙烧氧化法、生物氧化法、超细磨工艺、碱浸预处理及超声波技术等预处理方法的原理、优缺点;并指出,针对难处理金矿的高效选冶问题,未来应从技术创新、环保措施以及成本控制等方面开展进一步研究工作。难处理金矿选冶的未来发展趋势是向着更加高效、环保和经济的方向迈进,采用多种技术的联合预处理方案将成为重要的发展方向。研究结果为难处理金矿的预处理方法选择提供了依据。With the gradual depletion of easily treatable and high-grade gold ore resources,refractory gold ores have become the primary source of production in the gold industry.The gold in refractory ores typi-cally exists in the form of fine particles,forming complex compounds or inclusions with impurities such as sulfides and carbonaceous materials,making it difficult to effectively extract gold using conventional cyani-dation leaching methods.To improve the gold leaching rate,pretreatment technologies have become crucial.The current research status of pretreatment technologies for refractory gold ores,focusing on the principles,advantages,disadvantages of methods such as pressure oxidation,roasting oxidation,bio-oxidation,ultra-fine grinding,alkaline leaching pretreatment,and ultrasonic technology are systematically reviewed.Acco-ading to the problem of the efficient beneficiation and smelting of refractory gold ores,future research should focus on technological innovation,environmental measures,and cost control.The future develop-ment trend of refractory gold ore processing will move towards greater efficiency,environmental sustainabili-ty,and economic viability,with the adoption of combined pretreatment technologies becoming a key direc-tion.The research findings provide a basis for selecting pretreatment methods for refractory gold ores.
