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 ...

Energy Efficiency in Iron Ore Mining Electrical

The electrical energy accounts for less than 5 per cent of energy used in iron ore production. The major energy consumption is contributed by diesel used for transportation. Though scope exists for energy performance improvement in both forms of energy consumption, Diesel consumption is highly dependent on driving practices apart from proper maintenance of earth movers.

Understanding and using the Energy Balance –

The energy balance is derived from data which can be measured by national authorities. As such the energy balance is also an essential tool used to check data accuracy, as large statistical differences in energy units, apparent energy gains or large losses in transformation processes, or large unexplained variations in shares or in high-level indicators may all indicate underlying data problems.
