Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe by molecular weight.

اقرأ أكثرIron ore sintering and pelletizing are the predominant processes in the iron-making industry [1,2]. During the iron ore sintering process, calcium ferrite phase is believed to be the most desirable bonding phase because it has high reducibility and sufficient mechanical strength [3–5]. The sintering process can be divided into three procedures: (1) heating-up period.
اقرأ أكثرIron is most commonly extracted from the iron rock by way of blast furnace at very high temperatures. Iron ores can contain oxide and other impurities. When the ore is heated, it will separate the oxygen from the iron. Additionally, adding some calcium oxide will help remove the impurities, often called slag, from the iron. The iron industry has found that magnetite, …
