INTRODUCTION
• Iron in terms of production is within the top 5 of metals that are produced in the
world. It is mainly used in the construction sector.
• The most widely distributed iron-bearing minerals are oxides, and iron ores consist
mainly of hematite (Fe2O3), magnitite (Fe3O4), limonite or bog-iron
ore (2Fe2O3·3H2O), and siderite (FeCO3). Hematite and magnetite are by far the most
common types of ore.
• Pure magnetite contains 72.4 percent iron, hematite 69.9 percent.
• Deposits with less than 30 percent iron are commercially unattractive, and, although
some ores contain as much as 66 percent iron, there are many in the 50–60 percent
range.
• An ore’s quality is also influenced by its other constituents, which are collectively
known as gangue.
