Iron Ore an overview ScienceDirect Topics

Iron 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

Iron Ore Reduction an overview ScienceDirect Topics

The hot potassium carbonate process has been used effectively in many ammonia, natural gas, hydrogen, direct iron ore reduction, and ethylene oxide plants for many decades (Chapel et al., 1999). German patents using hot carbonate absorption of CO 2 can be found from as early as 1904 ( Kohl and Riesenfeld, 1985 ).

The Making of Iron & Steel

2020-8-3  Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
