EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE

2012-5-15 · Beneficiation of Camdag iron (oolitic) hematite ore containing limonite-hematite or goethite-limonite using gravity separation and high intensity magnetic separation, increases the grade of ore about 5-7% in concentrates with about 60% recovery by both methods (Guney et al., 2000). Abouzeid (1967) studied the possibility of using high intensity magnetic separator for the beneficiation of El-Gedida iron ore. An ore sample containing 51.6% Fe, 8.76% SiO2 and 3.06% BaO was used for the study. He found that high intensity magnetic separator tests were limited to very close range of sizes between 2 and 0.125 mm. The final magnetic product assayed 61% Fe at an iron recovery of 90.3%. However, 5% by weight was obtained as middling assaying 31.4% Fe. These middling products, together with the fine fraction minus 0.125mm which constitute 35% by weight of the whole sample, were not possible to be upgraded by magnetic separation.
