摘　　要：有色冶炼固废和难处理矿物作为金属资源的附载体,正在日益受到全世界的关注,高效提取其中的金属资源,对于固废的减量化或某些金属的战略安全具有重要意义。主要以氰化尾渣、红土镍矿、磁性废料、钒渣等有色冶炼废物和难处理矿石为关注对象,从氯化技术处理角度进行总结综述。对于某些含高价值金属(如Au、Ag等)的固废或难处理矿物而言,氯化技术有更大优势。Nonferrous smelting solid wastes and refractory minerals,as the carriers of metal resources,are receiving increasing attention all over the world.The efficient extraction of metal resources is of great significance for the reduction of solid wastes or the strategic safety of some metals.This paper mainly focuses on nonferrous smelting wastesand refractory ores such as cyanidation tailings,laterite nickel ore,magnetic waste,vanadium slag,and summarizes them from the perspective of chlorination technology.For some solid wastes or refractory minerals containing high-value metals(such as Au,Ag,etc.),chlorination technology has greater advantages.
