铟(Indium,In)为涂光炽[1]定义的8大分散元素之一,因其具有熔点低、沸点高及光渗透性和导电性强等物性特征,广泛应用于计算机、能源、电子、光电、国防军事、航空航天、核工业以及医药卫生,具有很高经济价值。In的克拉克值仅为0.052×10-9[2],主要从铜、铅、锌和锡石硫化物矿石中作为副产品综合回收利用。我国In资源丰富,主要分布于云南、广西、内蒙、青海和广东等地区[1,3]。滇西老厂大型银铅锌多金属矿床位于“三江”成矿带昌宁-孟连裂谷盆地南部,是成矿带南段[4-5]
Indium (In) is one of the eight disperse elements defined by Coke [1]. It is widely used in computers, energy, electronics, optoelectronics, defense and defense because of its physical properties such as low melting point, high boiling point and high light transmittance and conductivity. Military, aerospace, nuclear industry and medical and health, with high economic value. In Clarke value of only 0.052 × 10-9 [2], mainly from copper, lead, zinc and cassiterite ores as a comprehensive recycling of by-products. In China is rich in resources, mainly distributed in Yunnan, Guangxi, Inner Mongolia, Qinghai and Guangdong [1,3]. The large-scale silver-lead-zinc polymetallic deposit from the old factory in western Yunnan is located in the southern part of the Changning-Menglian rift basin in the “Sanjiang” metallogenic belt and is the southern part of the metallogenic belt [4-5]
