Available sources of iron oxide include high-grade lump ore, beneficiated iron ore fines, iron ore pellets, and agglomerates from dusts produced by the BF, basic oxygen furnace, and the EAF. Most DRI is produced in shaft furnaces, which require a uniform-sized coarse feed. Due to the high gas velocities and abrasive conditions in shaft furnaces ...

Pig iron is an intermediate step in the production of steel and is produced by smelting iron ore (commonly in lump, pellet or sinter form) in blast furnaces. Blast furnaces in Australia are located at Port Kembla and Whyalla. The removal, by oxidation, of impurities in pig iron such as silicon, phosphorus and sulfur and the reduction in the ...

Iron ore, in pellet or lump form or both, is introduced to the MIDREX reduction shaft. As the iron ore descends through the furnace, the reformed reducing gas reacts with the Fe 2 O 3 in the iron ore and converts it to DRI, leaving H 2 O and CO 2 as off-gas (Kolbeinsen 2010).

In the case of lump charcoal, the lumps aren't always perfectly carbonized meaning there is can be wood remaining. If there is uncarbonized wood, and there almost always is, it will combust and produce smoke and flavor. Both charcoal and gas grills produce combustion gases that impart flavor. Temperature is also a factor.

Reduction of iron ore in lump or pelletized form in the presence of coking coal entails a solid-solid reaction mechanism where the CO released from the coke directly permeates the surface structure of the iron ore to obtain a metallic iron as a by-product. But the challenge with the use of coking coal in the ironmaking process can be traced to ...
