Energy Efficiency in Iron Ore Mining Electrical India ...

18/12/2018  Process Overview: There are two basic methods of mining iron ore: Surface mining or open-cast mining; Underground or shaft mining. To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. The mines under energy audit study are open cast mines. The entire manufacturing is termed as ‘Mining’, where Iron ore is produced by open-cast mining.

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 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known
