The Midrex® and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The Circored and Finmet / Finored gas-based processes utilize iron ore fines as feedstock.The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock.

This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron ...

Iron ore is generally sourced from open pits on the planet's surface and typically requires only crushing before it is ready for the smelter. Like most mining, It all starts with a bang. Iron ore and its containing rock are blasted loose with high-explosives, making the ore accessible to machinery and small enough to be transported to the plant.

First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster. This produces what we have mentioned …

The iron ore fines and concentrate cannot be directly utilized in blast furnace, and therefore, its agglomeration i.e. enlargement of particle size is necessary before it is used as feed for iron making. Sintering is one of the methods of agglomeration. All iron oxide bearing wastes and coke breeze is used for sintering purpose.

In the Blast Furnaces, we melt iron ore into liquid iron at high temperatures. Iron ore has a sand-like structure that can put out the fire in the furnace. Because of that, you can't put it in the furnace just like that. The ore is first baked to make it into porous chunks, or sinters. This is done in the Sintering Plant. In the Pelletising ...
