Mining of Iron Ores – IspatGuru

The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface. Open pit and open cut mining are the least

Iron Ore Mining TechniquesMetal ExtractionTypes of Iron

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. The ores are generally prosperous in iron oxides and fluctuate in color ranging from dark grey, bright yellow, deep purple, to even rusty red. The iron by its own is usually found in the structure of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or siderite. Hematite is also identified as ...
