WEBFeb 17, 2024 · Iron Ore is a type of rock that contains iron minerals, mainly hematite and magnetite. It is a vital raw material for the production of steel. The ores are rich in iron oxides, which range in colour from dark grey to bright yellow to deep purple to rusty red. The most common iron minerals are magnetite, hematite, goethite, limonite, and ...
WEBApr 5, 2022 · During the process of iron ore pelletization and preparation of feed for DRI or reduction smelting processes, around 3% of pellet fines (less than 8 mm) are generated as undesired product in the existing pellet plants. Such pellet fines acquire more than 24 million tonnes generated all over the world. Recycling and reuse of these high grade ...
WEBOct 9, 2023 · The Circored process uses pure H 2 to reduce iron ore with a particle size less than 1 mm, and the reduction rate of iron ore powder for 15 min at 650 °C can reach 70%. To improve the efficiency of the entire production process, 4 h H 2 reduction of iron ore powder from CFB is needed to achieve a metallization rate of 95%.
Midrex Process. Midrex is the most successful gasbased DR process; it is a continuous process. It is basically a countercurrent process where a hot and highly reducing gas (95vol.% of this gas mixture being hydrogen and carbon monoxide with a ratio of H 2:CO varying from to ) reduces lump iron ore or pellets to metallic iron as .
WEBIn the iron and steel industry, direct reduction is a set of processes for obtaining iron from iron ore, by reducing iron oxides without melting the metal. The resulting product is prereduced iron ore. Historically, direct reduction was used to obtain a burr in a low furnace. At the beginning of the 20th century, this process was abandoned in ...
