Beneficiation Study on an Oolitic Hematite |

The oolitic hematite with a lower iron content and a higher phosphorus content will be a potential source of raw iron ore for the Chinese iron and steel industry The magnetization reducing roasted and magnetic separation is a practical beneficiation process The results show that the iron content in the concentrate can be increased to 5763% from 4595%, the iron recovery up to 7312%, whenBeneficiation of lowgrade finegrained hematite ores becomes increasingly important due to rapid depletion of high quality iron ore resources However, fine particles, especially ultrafine particles, make efficient beneficiation of these ores more difficult Therefore, methods to reduce the influence of fine particles must be considered to achieve better beneficiation performanceBeneficiation Study of an UltraFineGrained Hematite OreDetailed characterization and beneficiation of the banded hematite jasper (BHJ) from Joda area, eastern India, was studied The main purpose of this study is to produce a pellet feed from the BHJ ore using a simple flow sheet The feed sample contained total Fe (3531%), SiO2 (4873%), Al2O3 (058%) and loss of ignition (102%) Characterization studies such as grain size analysis, XRDStudies on Characterization and Beneficiation of Banded
