A low grade Banded magnetite quartzite BMQ from Obalapuram, D.Hiremandal, Ananthapur district,Andhra Pradesh, India was subjected to Diagnostic process characterization amenability study The scope of the procure evaluation study comprises of characterization, diagnostic process amenability gravity. and magnetic process concentration tests verging mesh of grand. The sample assayed 36.31 % Fe{t},42.72% SiO2, 5.12% FeO, 0,40% Al2O3, 1.14% MgO, 0,58% CaO, 0,31% alkalis, 0.13% TiO2 , 0.1%P, 0.05% S and 1.16% LOI. The sample contained mainly very fine grained hematite, magnetite associated intimately with fine grained quartz. Amphibole, goethite, apatite and pyrite were found in minor to trace amounts. The process diagnostic amenability tests to size, specific gravity and magnetic separation indicate that the sample is amenability to gravity separation at very fine size of -0.07mm . The sample is also amenable to magnetic separation at very fine size of -0.07mm yielding washery grade.. A combination of gravity and magnetic separation yields concentrates meeting the BF grade requirements at size finer than 0.07mm. The sample is amenable to beneficiation at very fine sizes producing either BF pellet grade concentrates or coal washery media grade concentrates.
