Iron Ore Pelletizing Process: An Overview IntechOpen

Jul 10, 2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process

Introduction to Iron ore Pellets and Pelletizing processes

It is an agglomerating process of converting iron ore fines into ‘uniformed sized iron ore pellets’ which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1.

Iron Ore Pellet an overview ScienceDirect Topics

In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based. In the gas-based DR process, the reducing gas is produced by chemically reforming

Ironing Out Savings In Iron Ore Cleaning Manufacturing.net

After being allowed to dry, the recovered dust and coarse particles are transported to a pelletizing system. Finally, the cleaned air can be released into the atmosphere. Not only does Pelletron boast that its system doesn’t lose any iron ore during the process, but its customer also attributes it with a much cleaner plant environment.

Direct Reduction Process an overview ScienceDirect Topics

Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum. The green pellets are then dried, preheated, and finally heated to a temperature below the melting point of iron oxides, approximately 1300 °C, to achieve strength.
