Iron | Geoscience Australia

IntroductionPropertiesUsesHistoryFormationResourcesMiningProcessingReferencesIron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, household appliances to buildings, bridges to railways, food cans to tools. In short, we rely on iron (as steel) to make almos…在ga.gov.au上更多信息

Iron | Geoscience Australia

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.

Goethite - HyperPhysics Concepts

This goethite sample was formed after pyrite when chemical conditions changed. It retains the pyrite's basic cubic shape, so it is a pseudomorph. Pyrite is an iron sulfide, and goethite is an iron oxide hydroxide. This compares the goethite sample with a cubic pyrite sample from Ambassaguas mine, Amejun, La Rioja, Spain.
