    Application of Response Surface Methodology on Beneficiation of Sudanese Chromite Ore Via Pilot Plant Shaking Table Separator.Mahmoud Motasim - 2020 - International Journal of Academic Multidisciplinary Research (IJAMR) 4 (5):63-73.
    High grade chromite ore has been decreased constantly due to the importance of chromium element in industrial uses such as metallurgical, chemical, and refractory industries. Therefore, beneficiation of low grade has been more significant .Response Surface Methodology (RSM) is combination of statistical and mathematical methods used for modeling and analyzing problems. In this study, the Central Composite Design (CCD) was applied by using Design-Expert (version 6.0.5) for modeling and optimizing the effect of operating variables on the performance of gravity separation (...)

    Characterization and Bond Work Index Determination of Low Grade Sudanese Iron Ore.Mahmoud Motasim - 2020 - International Journal of Academic Engineering Research (IJAER) 5 (4):13-19.
    In this study, the mineralogical, chemical characterization and physical properties of Sudanese iron ore in west of Omdurman city were studied using microscopic investigations, X-ray Diffraction analysis (XRD), X-ray Fluorescence (XRF) analysis, Atomic Absorption Spectrophotometer analysis (AAS) and the test of Bulk density. As well as, the Bond Work Index (BWI) and consumed power to grind one tone of iron ore were determined via standard Bond mill. The results showed that the ore is hematitic ore with Goethite and quartz minerals. (...)

    Beneficiation of Disseminated Low-Grade Sudanese Chromite Ore in Gedarif State at Umm Saqata-Qala Elnahal.Mahmoud Motasim - 2019 - Journal of Environmental Analytical Chemistry 6 (4):1-7.
    This study was performed on disseminated low-grade chromite ore, Gedarif State, Umm Saqata-Qala Elnahal, to treatment the ore by Heavy media separation (HMS) with low intensity magnetic separation (LIMS) for course fraction size (-212+75) μm and selective flocculation for chromite slimes (-75) μm. The ore of the study area is low grade contains 21.5% Cr2O3 with the liberation size of chromite mineral in the range (0.30-0.05) mm. The main gangue of the ore is mineral silicates as the Antigorite mineral. The (...)
