铁是钢铁工业的主要原料。钢铁需求的增加给印度的铁矿石资源带来了品位和储量方面的压力。随着对高品位矿石的需求相对于其有限储量的增加，采用先进的选矿技术，利用低至中品位铁矿石是当务之急。为了找到有效的利用途径，深入的矿物学研究是必要的，因为它揭示了与矿石有关的矿物学特性，这些矿物学特性影响到最终的选矿技术和最终产品。为了详细了解不同的矿物学属性，对奥里萨邦不同铁矿建造中的铁矿石进行了各种表征研究，包括宏观、微观(光学和电子)、X射线衍射、穆斯堡尔谱和VSM。论述了综合矿物学特征在铁矿选矿中的重要性。
Iron is a primary raw material for steel industry. Increase in demand for steel puts pressure on iron resources of India in respect of its grade and reserve. With increase in demand for good grade of ore vis-a-vis its limited reserve, the utilization of low to medium grade iron ores is the order of the day with adoption of advanced beneficiation techniques. In order to find out the effective way of utilization, an in depth mineralogical study is essential as it throws light on the mineralogical peculiarities associated with the ores which affect the resultant beneficiation technique as well as the final product. In order to have a detail insight into the different mineralogical attributes, various characterisation studies megascopic, microscopic (both optical & electron), XRD, mossbauer and VSM are undertaken on the iron ores from different iron ore formations of Orissa. Importance of integrated mineralogical characterisation in beneficiation of iron ores is discussed.
