    reserves are found with high content of haematite which ends up in tailings dam. These tailings can be subjected to beneficiation to yield a haematite concentrate containing 61.5 to 66% Fe and less than 3% SiO 2 (Filippov et al., 2014). In order to increase the efficiency of blast furnace, some of the issues relating to iron ores include chemical composition of iron ore with low Fe content and ...
