The reduction of wustite to iron was carried out at 1000, 900, and 800°C in a CO—CO2—H2 atmosphere for the mineral morphology-controlled sinter, and the following findings were obtained. The reduction rate of smaller amount of FeO led to faster increase of the reduction rate curve at the initial stage of reduction.

Maximizing Iron Unit Yield from Ore to Liquid Steel (Part 3 ... - Midrex

With 35% FeO in the slag, this means 7.8 kg of FeO or 6.1 kg of Fe lost to the slag. (Note: In this example, a relatively small change to accommodate phosphorus removal increased iron loss from 3.9% to 6.1%.) SERIES SUMMARY. Overall iron unit yield from ore to liquid metal can vary over a wide range via the direct reduction/EAF steelmaking route.

Iron ore - Wikipedia

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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Reduction of Iron Oxides with Hydrogen—A Review

In general, the reduction of Fe 2 O 3, called hematite, does not occur directly to metallic iron, Fe.If the reduction temperature is lower than 570 °C, reduction to Fe occurs stepwise from Fe 2 O 3 to Fe 3 O 4, called magnetite, and continues to Fe.The intermediate oxide, wüstite Fe (1−x) O, is not stable at temperatures lower than 570 °C. At reduction temperatures higher than 570 °C ...
