Much of the common ore of iron is a 'banded iron deposit' and this was created when, about 2.5 billion years ago, the earliest algae invented photosynthesis. This led to an oxygenated atmosphere, and this in turn allowed the iron; previously dissolved in the oceans; to be precipitated out as the oxide. This event is responsible for the banded iron deposits of North America, Australia, UK, and so on. The brown parts contain Fe2O3, and the black parts Fe3O4.
The names of the common iron minerals are magnetite, limonite, goethite, and hematite.
The origin of the iron is in the Earth's core, and this comes to the Earth's surface by volcanic action. Black volcanic iron sand is mined as a resource in several areas.

What are the common ores of tin?
The common ores of tin are cassiterite and stannite. Cassiterite is the primary ore of tin and is composed mainly of tin oxide, while stannite is a sulfide mineral containing tin, copper, and iron. These ores are typically mined for tin extraction.
What iron ores are found native?
Iron ores that are found native include magnetite, hematite, limonite, and siderite. These ores are typically found in a pure form in nature and do not require any extraction process to obtain iron.
Where was iorn found?
Iron is typically found in the Earth's crust in the form of iron ores, which are rocks and minerals from which metallic iron can be extracted. Iron ores are commonly found in countries with large deposits such as Australia, Brazil, China, India, and Russia. These ores are typically mined and processed to extract the iron for various industrial applications.
What is irons natural state in the ground?
Iron's natural state in the ground is typically found in the form of iron ores such as hematite, magnetite, and siderite. These ores are mined and processed to extract iron metal for various applications.
Where are some places iron can be found?
Iron can be found in sources such as iron ores (hematite, magnetite), meteorites, and in the Earth's core. It is also present in some foods like red meat, beans, and leafy green vegetables. Additionally, iron is widely used in manufacturing industries for making steel and other metal alloys.
What are the common ores of iron and lead?
Common Ores of Lead would be: Galena, which contains 86 percent metal...Anglesite, which carries 68 percent metal...Cerussite, which contains 77 percent metal...Pyromorphite,Mimetite and Wulfenite. Common Ores of Iron would be: Hematite (Hematite deposits are the most important source of Iron Ore in the United States.) Limonite,and Magnetite
What is the name of the main iron ores?
Two of the most common ores are Haematite and Magnetite, the most common being Hematite.Some others are Taconite, Goethite, Limonite and Siderite.
What are common ores?
Some common ores include iron ore (hematite, magnetite), copper ore (chalcopyrite), aluminum ore (bauxite), and gold ore (native gold). These ores are mined for their valuable minerals and metals used in various industries.
What is the compound in iron ore?
Common iron ores include Iron Oxides: Magnetite (Fe3O4) Hematite (Fe2O3) Other iron ores include Geothite FeO(OH) Limonite (FeO(OH).n(H2O))) Siderite FeCO3
What are the ingredents for iron ore?
Iron mainly comes from iron oxide ores, though less common ores such as the sulphide are used as available. There are usually many contaminants, such as silicon and phosphorous that need be removed by the refining process.
Which two minerals does iron come from?
I think the most common ores are magnetite and haemitite.
Does iron come from ores rocks or silicates?
Ores.
How do you make iron on Minecraft?
By smelting iron ores in the furnace, you'll earn iron ingots. Iron ores can be obtained by mining in generated caves.
What are the common ores of tin?
The common ores of tin are cassiterite and stannite. Cassiterite is the primary ore of tin and is composed mainly of tin oxide, while stannite is a sulfide mineral containing tin, copper, and iron. These ores are typically mined for tin extraction.
What are iron ores used for in France?

What are ores . name any 4common ores?
Ores are naturally occurring minerals that contain valuable elements or metals. Four common ores include iron ore (hematite), copper ore (chalcopyrite), aluminum ore (bauxite), and gold ore (native gold).
What non-silicate group contains iron ores?
The non-silicate group that contains iron ores is known as the oxide minerals. Iron oxide minerals, such as hematite and magnetite, are common sources of iron ore used in various industries like steel production.
