In the present work, the sample of the pyrite and aresenopyrite mineral were collected from Malanjkhand open pit mines of Balaghat district of Madhya Pradesh and Bhimsen Kila Pahar block of Bhandara district Maharashtra State to study the structural and physical studies of the samples in Laboratory. The samples has been characterized by X-ray diffraction technique and revealed that the first sample was possesses cubic crystal structure with pyrite structure and preferred orientation along (311) plane with the space group Pa3 and point group 2/m3. The value of lattice parameter a for the pyrite sample is found to be 5.417 ºA and the second sample was possesses monocline structure with arsenopyrite along (210) plane with space group P21/c and point group 2/m. The value of lattice parameter a, b and c are found to be 5.741 ºA, 5.668 ºA and 5.770 ºA respectively. The d.c. electrical resistivity measurement have been carried out over temperature range of 300° to 800°K. The temperature dependence of electrical resistivity exhibited activation energies. The magnetic susceptibility value are found to be 96.91 x 10-8m3kg-1 and 11.09 x 10-8m3kg-1 (S.I. unit). These values were compared with the standard data and showed that the samples are having cubic and monoclinic structure, semiconductor behavior and paramagnetic which become ferromagnetic after applied external field.
