Abstract: Hematite is a main source of iron. Some method for determination of major and trace element in iron oxide (Hematite Fe2 O3). Mineral using the Polarography and Atomic Absorption Spectroscopy was suggested. There are many valid reasons to analyze the trace elements content in different minerals to determine the purity of minerals, and to determine the presence of very rare and important elements which could be extracted and used to obtain data which give very important information on the geology of the mines and mineral localities. The investigation of the purity of iron minerals and rock is very important because of their utilization for iron and steel production. Sample preparation, procedures, Result of trace elements presence of Au(I) ,Bi(II) ,Pb(II) ,U(VI),Co(II) ,Ni(II) ,Zn(II) ,Mn(II) ,Fe(III) Cr(III) by Polarography method. Final analysis results on hematite ore sample Polarography Method is verified of standard additions for the metal investigated and minerals. An exact amount of standard solutions with a known concentration of identified metal was added to mineral samples the result confirm the presence of Au,Bi,Pb,U,Co,Ni,Zn,Mn,Fe,Cr, determinations and the percentage recovery levels are satisfactory results were obtained.
