摘要
铟(In)是一种稀散元素,它极少呈独立矿物出现,而是以其他矿物,例如金属硫化物、金属氧化物等为载体。近年来,随着对铟的年需求量不断上升,铟的市场标价一路走高,今后的上涨空间仍然很大。作者通过岩石矿物学和地球化学研究,初步发现四川岔河锡多金属矿区的铟含量很高,最高可达186.5×10-6,因此,推测此地区有很大的找铟前景。通过对铟与其它成矿元素的相关分析,发现该地区的铟与Zn、Cu、Fe、Cd、Sn、Ga都有明显的正相关性,由此推测铟可能存在于它们的金属硫化物、氧化物和(或)锡的氧化物中,进一步的电子探针工作发现,铟主要赋存于闪锌矿中,闪锌矿中最高含量可达500×10-6。因此,初步推断岔河地区铟有很大的找矿前景,应该考虑在今后的地质找矿工作和采选冶过程中加以综合评价和综合利用。
Indium （In） is a kind of dispersed element, rarely forms independent minerals itsself, is usally carried in metal sulfide or metal oxide minerals and so on. Recently, with the increasing of market requirement, the indium price increased, has rised to more than 9 million RMB per ton （according to the website of China Mining, Sep., 2005）, the highest one since 1965. Based on the study of petrology-mineralogy and the geochemistry, we found that indium content is as high as 186.5 × 10^-6 in the Chahe tin-polymetallic deposit, Huili, Sichuan, therefore, it is inferred that this area has an excellent prospect to exploit indium. Based on some relative analysis between indium and other oreforming elements, we found that there is positive relativity between In and Zn,Cu,Fe,Cd, Sn, Ga, therefore, indium maybe exists in their metal sulfide or metal oxide minerals. Furthermore, electronic probe analysis proves that indium mainly exist in sphalerite, in which the highest value of indium content is 500 × 10^-6. So it is necessary to synthetically use this tin-polymetallic deposit in the future.
