  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 ore was crushed, ground, and then classified to tow fraction size (-212+75) μm and slimes (-75) μm. Fractions size (-212+75) μm contained 25.58% Cr2O3 was treated by HMS via Bromofrom mixed with carbon tetrachloride flowed by low intensity magnetic separator. HMS with LIMS obtained the highest rec.. Read More»
