Method for reducing particulate iron ore to molten

Hydrogen 22 flows upward as hot gas 28 and reduces molten iron ore 29, producing molten iron 26. A byproduct of the reduction step is water vapor, which becomes part of hot gas 28. As the percentage of water vapor in hot gas 28 increases, the reducing potential of hot gas 28 decreases. Hydrogen 22 gas flow must therefore be adjusted so as to be ...

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite.Hematite is also known as "natural ore".
