摘　　要：论述了稀散元素钪在自然界中的分布、应用状况及提取技术。钪在自然界中极其分散,没有独立的矿物,多伴生在其他矿物中,但钪有着极为广泛和重要的用途,目前钪的生产主要是从钛铁矿生产钛白的废液和氯化物烟尘中回收钪。The distribution in nature, application, and extraction technology of scandium are introduced. Scandium is very rare in nature, there is not its independent mineral, it is usually symbiosis with other minerals, but scandium has very important and wide use. At present, most scandium was extracted from the waste solution of sulphale process for titanium white production or from the waste dregs of the chlorination of titanium rich materials.
