包括金、银的八种金属和铂族的六种元素（Ru、Rh、Pd、Os、Ir、Pt）被称为贵金属。自古以来，黄金和银因其优异的物理化学性质、稀缺性和美丽的金属光泽而受到特别重视。铂族金属是与金、银不同的现代贵金属，近年来，由于在电子、电镀、照相、催化等工业中的应用，对金、银和铂族金属的需求不断增加。因此，有必要建立含有贵金属的废料的回收技术。本文介绍了从废金属中回收金、银、铂等贵金属的几个实例。
Eight kinds of metals including gold, silver, and six elements of the platinum group (Ru, Rh, Pd, Os, Ir, Pt) are termed precious metals. Gold and silver have been especially valued since ancient times because of their excellent physico-chemical properties, scarcity, and beautiful metallic luster. In contrast to gold and silver, the platinum group metals might becalled the modern precious metals.Recently, the demand for gold, silver and platinum group metals has increased because of their applications in industries such as electronics, electroplating, photography, and emission control catalysis. Consequently, it is necessary to establish recycling technologies for scraps containing precious metals. This paper will describe some examples of practical perations to recover precious metals such as gold, silver, and platinum from scraps.
