Abstract
Instrumental neutron activation analysis (INAA) have been used to achieve accurate knowledge about the elemental analysis of hematite. The samples were prepared for irradiation by thermal neutrons using the irradiation facilities of the TRIGA Mainz research reactor. The gamma-ray spectra were obtained by using a hyper pure germanium detector. The value of iron concentration in our hematite samples of 57.7 % is in fair agreement with the results reported by other workers. From the economical point of view the hematite field is suitable for iron production due to its high iron content. Altogether, 32 elements were detected both qualitatively and quantitatively. In addition X-ray fluorescence XRF is used to detect other elements such as F, P, Si, W, Cu, Mo, Ni, Pb, Sr not determined by INAA. In brief, the presence of any elements in higher or lower levels is contingent on the occurrence of its bearing minerals, nature of parent sediments and depositional environments of these sediments.
