What are the forms of iron ore?
Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.
What are the 4 types of iron ore?
Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
What are the two types of iron ore?
The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. Ankerite is a carbonate of lime, magnesia, manganese, and iron.
What is the chemical formula of iron ore?
The most commonly used iron-bearing minerals contain iron compounds as follows: hematite, Fe2O3 (70% Fe); magnetite, Fe3O4 (72.4% Fe) and of much less importance are: limonite, 2Fe2O3·3H2O (60% Fe); siderite, FeCO3 (48.3% Fe); pyrite, FeS2 (46.6% Fe) [1]. These iron percentages are in their pure states.

How did Iron get its name?
The Latin name for iron is ferrum, which is the source of its atomic symbol, Fe. The word iron is from an Anglo-Saxon word, iren. The word iron is possibly derived from earlier words meaning “holy metal” because it was used to make the swords used in the Crusades, according to WebElements.
Who first started using iron?
In the Mesopotamian states of Sumer, Akkad and Assyria, the initial use of iron reaches far back, to perhaps 3000 BC. One of the earliest smelted iron artifacts known was a dagger with an iron blade found in a Hattic tomb in Anatolia, dating from 2500 BC.
Why is iron so special?
Iron is a “special” element because of its nuclear binding energy. The very basic idea is that when you fuse two light elements together, you get a heavier element plus energy. Similarly, if you have a heavy element that undergoes fission and splits into two lighter elements, you also release energy.
Will we ever run out of iron?
We will never run out of iron too because it comprises 5% of all Earth Crust. However, currently only those ores that contain above 50% iron are economic. We will not run out of glass at any point because it is made of sand which is silicon oxide, two of most common elements in Earth crust.
Will we ever run out of oil?
Technically speaking it is actually unlikely that we will ever ‘run out’ of oil. Oil, and all other fossil fuels are finite resources by their very nature, but as easier reservoirs of oil are exhausted other more complicated reservoirs become economically viable.
Can earth run out water?
Water, as a vapor in our atmosphere, could potentially escape into space from Earth. While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries.
