| Abstract | ||
| This study provides the mineralogical and compositional characterization of locally natural mineral clay deposits of Iraq which have been converted from hydrated aluminum silicate as their parents, grafted and enclosing rocks. The mineral assemblage of the raw clays of these primary deposits has been determined to include disordered bauxite , boehmite, quartz , gibbsite, calcite, in addition to trace amounts of other mineral clays like hematite and anatase. Such results have been investigated using powder x-ray diffraction, x-ray fluorescence, thermo gravimetric analysis, differential thermal analysis, infrared spectroscopy, and technical chemical analysis. Crystal structure and chemical composition of this bauxite rich mineral clays also have been performed to attribute that influence the industrial usage of Iraqi natural mineral clays are highlighted. | ||
