In the present study a detailed characterization followed by benefciation of low grade iron ore was studied. The Run of Mine (R.O.M) sample assayed 21.91 % Fe, which is very low grade in nature. The impurities are SiO2 26.25%, MgO 20.48%, CaO 5.85%, Al2O3 1.86% and loss on ignition (LOI) 12.71%. A Davis Tube test was performed for the assessment of the separability of magnetic ores by low intensity magnetic separators. The heavy liquid test was carried out to evaluate the possible response of the sample by the gravity concentration technique. The samples were subjected to jigging, dry low intensity magnetic separation (DLIMS) and shaking table tests. Thus a suffcient concentrate could not be obtained in +1 mm by using jigging and DLIMS. The obtained results show that the a high grade iron concentrate (>65% Fe) with lower recoveries was obtained from shaking table tests by using -1 mm fraction. According to the results a fowsheet was developed. From the developed fowsheet, it is possible to obtain pellet grade concentrate with 65.41% Fe, 2.54% SiO2, 2.79% MgO, 0.70% CaO and 0.32% Al2O3. with 21.42% weight recovery. The overall gangue rejectio\n recovery of the circuit is over 95%. [ABSTRACT FROM AUTHOR] |
