For the past decades researchers are showing immense interest to investigate the natural advantage of preparation of composites from minerals such as bauxite particles, and proved their effectiveness as cost effective reinforcing agents in fabrication of high performance composites. This study, is a new attempt in using the Iraqi natural bauxite powder with different proportions (2wt%, 4wt%, an...

Bauxite deposits of Jharkhand in India are resulted from the lateritization process and therefore are often associated with the laterites. In the present study, ASTER (Advanced Space borne Thermal Emission and Reflection Radiometer) image is processed to delineate bauxite rich pockets within the laterites. In this regard, spectral signatures of lateritic bauxite samples are analyzed in the labo...

The effect of alkaline leaching on the recovery silicon elements from Iraqi Bauxite Ore. was examined NaOH concentration, particle size, and stirring speed using program MINITAB 16. concentration (X1) (1,2, 4M), size (X2) (53,75, 150µm), (X3) (250,500, 750 rpm). best percentage found to be (94.1097) when variables were (X2= 53µM), (X1 = (X3=750 (X1), (X2), have a substantial influence process r...

The present work is especially concerned with the Iraqi bauxite ore that includes 4.1% of titanium element (Ti). goal this study to investigate effect various parameters (concentration acid, ratio solid: liquid, stirring speed, contact time, and temperature) in order determine best conditions for leaching extraction element. All tests were conducted different acids (HNO3, H2SO4, H3PO4) a liquid...

In order to develop low-temperature (below 200 °C) and SO2-tolerant catalysts for selective catalytic reduction (SCR) of NOx, a series of cheap M/bauxite (M = Mn, Ni and Cu) catalysts were prepared using bauxite as a support. Their SCR performances are much superior to typical V2O5/TiO2, the addition of M into bauxite results in significant promotion of NOx removal efficiency, especially at low...

The rapid development of the global aluminum industry has led to a considerably increasing consumption of bauxite, from which alumina is mostly produced. Many aluminum producing countries including China have to import bauxite to keep the growth of native industry due to the low quality of bauxite. The costs of alumina production as well as the other aluminum-related products are correspondingl...
