分散元素通常是指镉、镓、锗、铟、硒、碲、铊和铼等8种元素,这些元素在地壳中的平均含量低(一般为10.~10~(-6)级),不易形成独立矿物,难以发生有意义的富集~([1~4]),属于急需、急缺性资源。长期以来,分散元素多被作为其他矿床的伴生组分,主要侧重于含量、赋存状态、综合回收等方面的研究~([5~6]),对分散元素矿床的研究没有给予足够的重视,有关分散元素矿床的研究程度总体上仍很低~([7~9])。关于铟元素的研究主要始于20世纪50年代,侧重于铟
Dispersing elements usually refers to 8 kinds of elements such as cadmium, gallium, germanium, indium, selenium, tellurium, thallium and rhenium. The average content of these elements in the crust is low (usually 10 ~ 10 -6), not easy The formation of an independent mineral, it is difficult to meaningful enrichment ~ ([1 ~ 4]), is a much-needed, emergency resources. For a long time, scattered elements are often used as an accompanying component of other deposits, mainly focusing on content, occurrence state, comprehensive recovery and so on ~ ([5 ~ 6]), did not pay enough attention to the study of dispersed element deposits , The degree of research on dispersed elemental deposits is still generally low ~ ([7 ~ 9]). The study of indium mainly began in the 1950s with a focus on indium
