岩矿鉴定在某稀土矿石中的应用

Application of rock and minerals ore identification in a rare-earth ore

岩矿鉴定是指应用各种矿物学原理与方法,通过矿物的光、电、声、热、磁、重、硬度、气味等以及其主要的化学成分特征,对岩石、矿物样品、包括光(薄)片、砂片、碎屑、粉末进行观察、鉴定以区别其矿物类别,以及研究岩石、矿石的主要矿物组成、矿物成生序列,结构、构造、岩(矿)石类型的技术方法。本文以含稀土碳酸岩为例,结合3件样品的光片鉴定和薄片鉴定,从而确定其矿物成分可由氟碳铈矿、独居石、白云石、方解石、方铅矿、磁铁矿等矿物组成。

Rock ore appraisal principle and method is refers to the application of mineralogy and mineral through sound,ele ctricity,light,heat,magnetism,weight,hardness,smell,and its main chemical composition characteristics,such as rock and mineral samples,including light(thin),sand pills,debris,observation and identification of powder to distinguish its mineral categories,as well as the study of rock,the main mineral composition and mineral ore into raw sequence,structure,structure,rock(ore)types of technical methods.In this paper,the rare-earth carbonatite is taken as an example,and combined with the light sheet identification and thin section identification of three samples,it is determined that its mineral composition can be composed of fluorocarbon cerite,monazite,dolomite,calcite,galena,magnetite and other minerals.
