Goa state in India is endowed with large deposits of low-grade iron ores, geologically formed from the lower Dharwar super group of Archaean rocks. Petrological studies have revealed that silica and alumina are the main gangue minerals, where alumina exists as fine clay and adherent material interspersed in the ore body. The amenability of column flotation and dual extraction column to remove such gangue was studied by installing test units at the Greater Ferromet beneficiation plant of M/s. Sociedade De Fomento Industrial Ltd. A reverse flotation process was adopted wherein gangue minerals containing silica and alumina are floated using a cationic collector. Sodium hydroxide and starch were used to regulate the slurry pH and depress the iron ore, respectively. Different iron ores and their mixtures were studied using various cationic collectors. The results indicated that iron ore concentrate assaying 67% Fe and 2% SiO2 and Al2O3 could be obtained with a recovery of 85-90% by single stage column operation. The study demonstrated that flotation column outperformed the dual extraction column in terms of gangue reduction. Overall, these findings underscore the effectiveness of flotation technology in enhancing iron ore recovery in the region.
