Mining. Most iron ores mined today comprise the iron oxide minerals hematite, Fe 2 O 3 (70% Fe); goethite, Fe 2 O 3 s H 2 O, (63% Fe); limonite, a mixture of hydrated iron oxides (up to 60% Fe); and magnetite, Fe 3 O 4 (72% Fe). As with most iron ore mines throughout the world, all the major Australian iron ore mines are open cut.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
The iron ore mine currently has an abundance of OFF grade ore stockpiles due to the prioritising of ON grade ore at the plant. Stockpiling is included in the five-year and 12-month rolling plans. If the ore that is mined is more than what the plant can process, it is then sent to the stockpiles.
The process of mining starts with the discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location ...
