Mineralogical and Beneficiation Studies of a Low
2014-7-26 Normally iron ores with 65 % Fe content and above are desirable to achieve better productivity either through blast furnace or direct reduction for the metal iron production. Iron ore with low Fe content and high Al:Si ratio can not be used directly in any of the processes. This has been mainly due to the presence of high levels of impurities such as silica and alumina in the raw materials. Therefore, research on beneficiation and utilization of low grade iron ore
