The global iron producing industries are trying to use the high alumina content iron ores due to the exiguity of high grade ores and economic reasons For this purpose this present study focuses on the utilization of high alumina hematite iron ores obtained from eastern part of India in pelletization experiments The effects of firing temperature and time and binder addition on compressive
·Many workers from different disciplines such as geology chemistry medicine and biology are interested in these compounds Recently developed techniques such as Atomic Force Microscopy AFM Fourier Transform Infrared FTIR X ray photoelectron spectroscopy XPS and Mössbauer spectroscopy are being applied to elucidate details of interior and
·Analysis of the current technical solutions for the processing of iron ores showed that the high grade ores are directly exposed to metallurgical processing; by comparison low grade ores
·Present investigation includes the magnetizing roasting of low grade iron ore fines followed by grinding and beneficiation using magnetic separation The hematite iron ore used in the investigation contains % T Fe % SiO2 and % Al2O3 Powdered bituminous coal of 210 μm size with an ash content of % and fixed carbon of % was
·Twenty different iron ore pellets consisting primarily of Hematite Fe2O3 phase were subjected to simulated reduction studies A wide range of reduction time periods Rt of 122 to 211 minutes were obtained Detailed microstructural characterizations were then conducted at different locations of ten selected specimens The Rt did not relate with initial phase mix or
·Magnetite hematite ore of the Mikhailovskoye deposit Russia was chosen as the object of research The Mikhailovskoye deposit is located in the Kursk region of Central Russia and has unique reserves of iron ore The iron ore stratum belongs to the Proterozoic ferruginous siliceous shale formation of the lower Karelia Kursk type
·The interaction between mineral phases in two commercial iron ores and flux materials CaO MgO SiO2 and Al2O3 was studied under kPa O2 partial pressure while heating to different temperatures CaO was the most effective flux for liquid phase generation during sintering For a hematite ore with few gangue components Ore A the formation of an
