粤西含锡稀有金属主要分布于郁南、云浮、德庆及广宁四县。伟晶岩矿床主要产于下古生代变质岩和海西—燕山期花岗岩小侵入体的接触带附近。矿床中锡石普遍含钽铌,而且含量较高。对本区矿床所产锡石中钽铌的赋存状态及其回收可能性问题。作者曾在有关专业单位的协助下,进行了一些研究和探索工作,现简述如下。 The tin-containing rare metals in western Guangdong are mainly distributed in four counties: Yunan, Yunfu, Deqing and Quang Ninh. The pegmatite deposit is mainly produced near the contact zone of the Lower Paleozoic metamorphic rocks and the small intrusions of the Hercynian-Yanshanian granite. Cassiterite deposits generally contain tantalum and niobium, and high levels. Occurrence of tantalum and niobium in cassiterite produced in this area and the possibility of its recovery. The author has conducted some research and exploration work with the help of the relevant professional units and is summarized as follows.
