摘要:
铜矿资源“贫细杂”的赋存特征，使伴生贵金属高效回收已成为保障国家战略资源供给安全的重要课题。针对铜矿及伴生金银回收率低的技术瓶颈，系统分析了铜及伴生贵金属的工艺矿物学特征，重点阐述了浮选富集、湿法提取及选冶联合工艺路径；提出选冶联合工艺的增效机制，通过再磨技术、新型捕收剂及闪速浮选装备的应用，显著提升铜、金、银综合回收率；对比分析了湿法提取氰化法与非氰化法的优劣，指出了发展低毒浸出剂与智能化控制策略的重要性。

Abstract:
The occurrence characteristics of copper ore, namely "low grade, fine dissemination, and complexcomposition," have made the efficient recovery of associated precious metals an important issue for ensuring the securityof national strategic resource supply. Aiming at the technical bottleneck of low recovery rates of copper and associatedgold and silver, this paper systematically analyzes the process mineralogy characteristics of copper and associated preciousmetals, with emphasis on flotation enrichment, hydrometallurgical extraction, and combined beneficiation-metallurgyprocess routes. The efficiency⁃enhancing mechanisms of the combined process are proposed; through the application ofregrinding technology, novel collectors, and flash flotation equipment, the comprehensive recovery rates of copper, gold,and silver can be significantly improved. The cyanidation and non⁃cyanidation methods for hydrometallurgical extractionare comparatively analyzed, and the importance of developing low⁃toxicity leaching agents and intelligent control strategiesis highlighted.
