“…So probably the previously described process is responsible for the formation of these deposits. Usually, the element Y follows the rare earth elements (REEs) in nature 17 . There is a poor positive correlation (Table 2) between Y and Fe observed, which indicates that Fe may be the carrier of Y as well as REEs.…”

Precambrian ferromanganese oxide deposits of India and Brazil were formed in optimum favorable geological situations at specific period of evolution. Two representative ferromanganese oxide ore samples have been collected from different mines of Precambrian Bonai-Keonjhar belt, Eastern India, and were irradiated with 3 MeV proton beam from a 3 MV pelletron accelerator at Institute of Physics, Bhubaneswar, India. The spectral data were analyzed by using GUPIX software package. About 20 major, minor and trace elements including Ca, Ti, V, Cr, Co, Ni, Cu, Zn, Ga , As, Se, Rb, Sr, Y, Zr, Mo and Pb were quantified in these ores. The obtained Mn/Fe ratio and the content of the trace elements were used in interpreting the initial formation environment of the depositional basin.

“…Mossbauer spectroscopy has been used for identification of iron bearing mineral phases [3]. Earlier workers have reported mineralogy of Iron ores from banded iron formations of Orissa by means of Mossbauer spectroscopy [4]. For the present investigation, selected samples from three iron ore formations were taken for Mossbauer study.…”

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 visa -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.

“…Other ion beam techniques such as PIGE is better than PIXE when measuring some elements especially the low Z elements as self-absorption effect is completely avoided [2,3]. PIXE has many applications in the study of archaeology, environmental, biological, medicinal and forensic materials [4][5][6][7][8][9]. However, despite the numerous advantages of PIXE technique, standardization or calibration with certified reference materials before each experiments poses a major challenge to most researchers [10].…”

Standardization of proton induced X-ray emission for analysis of trace elements in thick samples

This paper presents the standardization of Proton Induced X-rays Emission (PIXE) technique for the trace element analysis of thick standard samples. Three standard reference materials (SRMs) viz-à-vis titanium, copper and iron base alloys were used for the study due to their availability. The protons beam was accelerated up to 2.57 MeV energy by 5UDH-II tandem Pelletron accelerator and samples were irradiated at different geometry and durations. Spectrum was acquired using a multi-channel spectrum analyzer while spectrum analysis was done using a GUPIXWIN model for determination of elemental concentrations of trace elements. The obtained experimental data was compared with theoretical data and results were found in close agreement.
