摘要
铯是稀有轻碱金属,在现代高科技领域具有广泛的应用前景,本文重点分析了我国铯矿资源类型及其主要分布。铯是碱金属元素,因此主要产于碱性岩中或盐湖中,与碱金属锂、铷,稀有金属铌、钽及稀土等共生或伴生。我国的主要铯矿矿床类型可以划分五种产出类型,即碱性花岗伟晶岩中的铯榴石矿床;铌钽矿床中伴生铯矿;风化沉积型铯铌矿;
Caesium,a rare alkalecent metal,is of a wide range of applications in modern hi tech area.The paper focuses on analyzing the type of Cs bearing deposit resources and its distribution.Due to Caesium's attribute of alkali metal,it mainly occurs in alkali rocks and salt lake,often accompanied by metals such as Li and Rb,and rare metais such as Nb and Ta.According to the type of Caesium bearing deposits,there are five kinds of occurrences The pollucite deposit in alkali gramatic pegmatite,the associated Caesium deposit in Nb and Ta deposit,meathering and sedimentary Caesium deposit, Caesium bearing brine and the Caesium bearing silicious rock in modern geothermal regions.
