Received November 10, 1990; in ﬁnal form March 20. 1991. The efﬁciency of reduetion-roasting/magnctic separation of hematite, goethite and any extremely ﬁne- graincd iron ore. which is non-responsive.Magnetizing roasting mechanism and effective ore dressing process .Apr 30, 2011 . Magnetizing roasting of oolitic hematite ore from western Hubei Province was investigated. The mechanism for reduction roasting of oolitic hematite ore was discussed and analyzed. It is found that.
recovery of iron from low-grade hematite ore using coal-based direct .Therefore, it is difficult to obtain a high grade iron product directly using traditional mineral processing techniques 3,4 . It is well nown that the magnetizing roasting or direct reduction magnetic separation is an effective method for iron recovery from solid tailings 2 6 . Low grade iron ores are also another example.Beneficiation of Low Grade Iron Ore Fines by Magnetizing RoastingKeywords: Magnetizing Roasting, Goethitic iron ore, Hematite, Magnetite. *Corresponding Author: Jyoti Sharma eng.jyotisharmagmail. INTRODUCTION. Due to depletion of high grade and medium grade iron ore, it has become essential to use low grade ores and rejects after proper beneficiation. Conventional.
