Iron Ore Mining Techniques Metal Extraction

The iron by its own is usually found in the structure of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite. Hematite is also identified as "natural ore". The nomenclature dates back to the early years of drawing out, when certain hematite ores comprised 66% iron and could be fed reliably into iron edifice blast furnaces. Iron ore is the unrefined substance utilized to ...
