Characterization and flotation studies were carried out on a slime sample from a low grade iron ore belongs to Gua mines of SAIL with a view to develop flotation based process for its up gradation to pellet grade concentrate. From the mineral characterization studies, it was observed that hematite, goethite and martite were iron bearing phases while kaolinite and quartz were its major gangue. The iron ore slimes assayed 52.55% Fe with 10.8 % SiO2 and 9.3% Al2O3. The sample deslimed prior to flotation using hydrocylone to remove the ultrafine particles. Detailed flotation studies were...
