一、绪言铟是稀散金属中的一个,它在自然界中不构成单独的矿物,而经常存在於闪锌矿,特别是暗闪锌矿——即含铁、锰较多的闪锌矿中,其他如硫化铅矿、锡矿、硫化铁铜矿及某些钨、锰、铁矿中亦含有铟,但因一般含量很少,故没有直接提炼的价值及可能。目前世界各国提炼铟都是由铅锌冶炼过程中的废品或副产品中回收,因此在决定回收铟前及提炼铟的过程中,必须对这些产品或中间品进行分析测定,明瞭铟的分散与集中的情说,以便决定何种产品适宜於回收并检查提炼铟过程中铟的浓缩过程。
I. INTRODUCTION Indium is one of the rare earth metals that does not constitute a separate mineral in nature and is often present in sphalerite, especially in the dark sphalerite - the sphalerite with more iron and manganese, Other such as lead sulfide, tin, iron ores and some tungsten, manganese, iron ore also contains indium, but because of the general content is very small, so there is no direct refining value and possible. At present, all countries in the world extract indium from the lead-zinc smelting process by-products or by-product recycling, so in determining the recovery of indium before and during the extraction of indium, these products or intermediates must be analyzed to determine the indium dispersion and concentration In order to determine what kind of product is suitable for recycling and checking the concentration of indium during the refining of indium.
