Ore Composition of Lege Worke - Dasu Blocks of Iron Mineralization, Northern Ethiopia

Iron existed in the form of oxides and also, it is mostly abundant as well as the dominant resource of the Earth for the constrictive industries of the world. The iron ore mineralogy of iron is mainly concentrated as hematite, goethite and magnetite oxides minerals. Beside those oxides the siderite, illmenite and many other are common iron ores. The Lege Worke -Dasu blocks of iron found in the Northern and northwestern part of Ethiopian plateau. This research study holds the main objective of determining the mineralogical composition and mineral assemblage of the iron ore mineralization of the Lege Worke - Dasu blocks. The geological field work with lithological mapping, reflected microscope (ore) petrographic study, mineralogical study using (XRD), and geochemistry of major and other elements were the most applied methodologies for this study. The mineralogical study of the Lege Worke - Dasu iron mineralization result shows that the iron ore body samples were characterized in terms of their mineralogical composition. The outcome result indicates that the ore body consists mainly hematite and goethite iron ore minerals are the dominant compositions documented from the polished section and XRD result. The outcome results of analyzed chemistry and ore study from the polished section studies are shows that the layered (laminated) and pisolitic textures of hematite ore, goethite ore compositions are the main outcomes of this research study. In addition to those ore mineralogy kaolinite gangue, anatase minerals are common constituents including quartz as a gangue mineral. Major oxide analyses for systematically selected samples were characterized by SiO 2 , Al 2 O 3 and Fe 2 O 3 and others. The whole rock chemistry of iron ore and surrounding rock of Lege Worke - Dasu blocks of iron mineralization were used to determine the iron mechanism of the current research area.
