Iron making. The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group …
Iron | Geoscience Australia
Properties. In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.
