Iron Rich Minerals in Rock Pointed in One Direction.


Then y’all are wondering what minerals have iron in them.  Y’all might be surprised to know that only a few minerals have a good amount of iron in them.  Lucky for u.s., iron contained in these few minerals are quite abundant on our earth, as atomic number 26 has proven to exist quite useful.


Retrieving iron in minerals has been around for thousands of years.  In that fourth dimension frame, it has been constitute that minerals with larger quantities of iron include pyrite, magnetite, chalcopyrite, hematite, goethite, limonite, greenalite, and siderite.

The minerals with the highest iron content will be magnetite, hematite, goethite, and limonite.  These minerals range in about 60% to lxx%+ in iron content.  Magnetite is the most widespread mineral on earth with roughly the highest iron content.

Percentage of Fe (Approx.)

Chemical Formula
Magnetite ~72% Fe2+Fe3+

Hematite ~69% Iron2Oiii
Limonite ~60% FeO(OH)·due northH2O
Siderite ~48% FeCO3
Pyrite ~46% FeStwo
Chalcopyrite ~30% CuFeSii
Goethite ~63% FeO(OH)
Greenalite ~44% (Fe2+,Feiii+)2-3SiiiO5OHiv
This tabular array shows the estimate per centum of atomic number 26 in the mineral.  These Iron bearing minerals volition often be contained within what people call atomic number 26 rock or iron ore.

Extraction from Iron Ore

Atomic number 26 ore, or iron rock, is the host rock in which atomic number 26 rich minerals can be extracted.  The most commonly extracted minerals inside iron ore are magnetite, hematite, goethite, and siderite.  Iron is most commonly extracted from the iron rock by way of blast furnace at very loftier temperatures.

Atomic number 26 ores can contain oxide and other impurities.  When the ore is heated, it will separate the oxygen from the iron.  Additionally, adding some calcium oxide will help remove the impurities, often called slag, from the iron.

The atomic number 26 industry has found that magnetite, hematite, goethite, and siderite are the best sources for extracting iron for a good reason.  These minerals contain fewer impurities such as sulfur or phosphorus, which can make atomic number 26 brittle and difficult to work with.


The most common types of loftier class fe ore mined for its iron will be massive hematite, magnetite, titanomagnetite, and pisolitic ironstone.  These iron ores tin can incorporate minerals loftier in atomic number 26 content besides every bit minerals that have cleaner, or more pure fe.

Rocks with the Nigh Fe

The almost common kind of rock that contains minerals with iron are sedimentary rocks.  For a stone to be considered iron rich, it must contain 15% or more iron in its composition to qualify.  Some great examples of potential iron rich sedimentary rocks are sandstone, black shale, and dolomite.

A practiced fashion to tell if a rock has iron in it volition exist by seeing a metallic color or luster within the rock.  For rocks like quartz rich sandstone, you can see cherry-red, brown, and even yellow banding.  This banding is the indication of fe within the host stone.

Colour does play an important function in identifying types of iron.  Ferrous atomic number 26, iron (II) will accept a dark-green colour.  Ferric iron, fe(Three) will frequently have colors that are reddish or brownish.


The red in this sandstone would indicate that there is iron contained within it. Notwithstanding, it is not likely to contain enough iron for whatever sort of extraction.

How Difficult are Minerals with Iron

Iron has a hardness of four on the Mohs calibration of hardness.  Though the Mohs scale of hardness is typically used for minerals, frequently metals like iron are compared.  Iron is compared to the same hardness as the mineral fluorite.

Chemical bonds in minerals containing iron can be stronger than just the extracted iron itself.  Hematite and magnetite are great examples of that both coming in at nigh five.5 to 6.5 on the Mohs scale of hardness.

With refinement and processing iron can be purified and besides combined with other metals.  Steel can be slightly harder than fe equally information technology is processed and impurities are removed.  Hardened steel can autumn at around an 8 on the Mohs scale of hardness.

Places where there are Minerals with Iron

Minerals with iron are constitute all over the world.  Larger iron mineral deposits can exist found in Australia, Brazil, China, India, Russia, and the USA.  As these countries have an abundance of atomic number 26, you might expect that they may likewise produce the most.


The most mined and biggest exporter of Atomic number 26 ore in 2019 was Australia.  Equally time goes on that may change, though currently Brazil, China, India, Russia, and United states are all very distant in production comparatively.  Run across “Listing of countries by iron ore production”. (Wikipedia reference for Atomic number 26 ore production by state)
