印度奥里萨(Orissa)邦苏金塔(Sukinda)地区含镍红土矿石由很细的颗粒聚结成大聚合体而组成,矿石的化学和矿物学性质复杂,并有许多特点和选矿上的问题。本文讨论了用几种技术鉴定矿石特性详细的研究结果。特性鉴定所采用的各种工艺包括:元素分析、电子显微镜、用于化学分析的电子分光光度计、X射线和电子衍射、差热和热重分析、能量散射X射线分析(EDAX)、穆斯鲍尔(Mossbauer)方法和红外线光谱。通常一种方法辅以它种方法,说明要充分鉴定这个矿石的特性几种技术联合是必要的,也讨论了这些技术的使用范围和限度。
In the region of Orissa, Sukinda, India, nickel-bearing laterite ores are composed of very fine particles coalesced into macro-aggregates. The ores have complex chemical and mineralogical properties and many characteristics and beneficiation problem. This article discusses the detailed findings of the identification of ores using several techniques. Various techniques used in characterization include: elemental analysis, electron microscopy, electronic spectrophotometer for chemical analysis, X-ray and electron diffraction, differential thermal and thermogravimetric analysis, energy dispersive X-ray analysis (EDAX) Mossbauer method and infrared spectroscopy. Usually a method is supplemented by a method that illustrates the need to fully identify the characteristics of this ore combination of several technologies and discusses the extent and limits of their use.
