- The Angooran Lead & Zinc Mine located in Zanjan province, Iran is one of the largest ones of its kind in the Middle East. At present, a part of the ore body located within host rock mineralised schist is not included in the milling design. According to previous work, wet chemical assay, XRF, XRD and ore microscopy studies of the ore samples show that the ore contains Smithsonite (16%), Mimetite (0.6%), Quartz (52%), Sericite (16.5%), Kaolinite (12%), Iron Oxides Minerals (1.5%), Rutile (0.4%) and other minerals (1%). (Hosseini S.H. et al ,2001) In the present study, XPS (ESCA) and EDX have been utilized, in order to study the characterization of the surface and bulk composition respectively for three fraction of - 250, +200 μm; -200, +150 μm and -150μm. The results of XPS show that these have no difference especially in Zn percentage and also for other elements for three size fractions. It can be concluded that the surface composition are approximately the same for both three-size fractions. A comparison between the data obtained from XPS (Surface Composition) and from EDX Analysis (Bulk Composition) shows that there are some differences for the Si, Fe, and Al content in the ore sample and these differences between XPS and other techniques should be based on the amount of Oxygen for each technique.
