coal based sponge iron plant using magnetite ore

How is sponge iron made Answers. Now a days,sponge iron is a name in steel making process.There are different methods to manufacture sponge iron but in India largely coal based process are carried out.In this process iron ore lumps (520mm)are feed into a horizontaly inclined vessel named as Rotary kiln (length 40mt. and .

Modelling of heat recovery in LKAB's gratekiln process

These two zones serve to increase the temperature of the pellets prior to the kiln, and here the main part of the oxidation to hematite takes place [9]. Oxidation of the pellets releases a large amount of heat – this is the main heat source in the process[5]. The heated pellet bed then enters the rotary kiln, shown schematically in Figure 2.2.

SL/RN process Outotec

The SL/RN process was developed in the early 1960s by Outotec in collaboration with three US companies. The process principles are the basis for numerous rotary kiln plants and still represent the dominant technology for the direct reduction of lump ore or pellets using coal.

NOx formation in iron ore rotary kilns

Iron ore pellets are often produced using the socalled GrateKiln process, which is designed to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this process comes from the combustion of a pulverized fuel in a rotary kiln, involving the formation of a jet flame.

dry process of magnetite iron ore beneficiation

The results show that the nickel slag is dominated by magnetite, maghemite which is higher than the average iron grade of iron ores (32% Fe) in China. After that, the compositions of both dry magnetic and nonmagnetic Get Quote WO2013138889A1 A process and system for dry recovery of iron

NOx formation in iron ore rotary kilns

The GrateKiln process, applied in the iron ore industry, is an example of an industrial process that is attracting increased attention regarding emissions reductions. The GrateKiln process applies combustion of a fuel together with large volumes of preheated (>1000°C) air in a rotary kiln, so as to provide heat for the iron ore.

Iron Ore Pelletizing Process: An Overview IntechOpen

In the case of magnetite, heat generation is more uniform over the pellet volume, while for hematite it will be concentrated around carbon particles that must be evenly distributed. This is the reason for using very fine solid fuels such as anthracite or coke breeze in the mixture to be agglomerated during balling. In the gratekiln process

Direct reduced iron Wikipedia

Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles.
