Hasançelebi iron ore deposit is located at 94 km northern west of Malatya, close to the Hasançelebi town and is one of the most important iron ore deposits known in Turkey with a geological reserve of 3.2 billion tons. Since 1975, several investigation projects including intensive feasibility studies were realized on Hasançelebi iron ore deposit; however, no one had been found feasible, therefore, the ore deposit has not been operated up to now. The new project entitled 'Re-evaluation of the Malatya-Hekimhan, Hasançelebi Iron Ore' subjected to this paper was awarded to Mineral and Coal Processing Section. Concentration results as a part of the whole project are discussed in this paper. Pre-concentration and direct concentration studies were realized on laboratory and pilot scale in order to develop a process flow sheet including material balance. The tests were conducted on the representative ore sample containing 25.9% magnetite. Pre-concentration tests were carried out on this sample with the particle sizes of minus 4 mm. As a result of experiments, a concentrate with 23.4% by weight of the original ore, assaying 69.15% Fe with a recovery of 74.8% was achieved. Meanwhile, direct concentration with run-off mine ore on minus 0.074 mm yielded a concentrate with 24.2% by weight, assaying 69.10% Fe, with a recovery of 74.7%. Although results seem compatible for both cases, valuable energy savings can be obtained for fine size grinding from pre-concentration application.
