Pure iron is a bright silverywhite metal which oxidizes (rusts) rapidly in moist air or in water containing dissolved oxygen. It is soft, malleable, and ductile, and is strongly magnetic (ferromagnetic).It is rare to find it in elemental form on the Earth, but the sample at right was found in Greenland. It has also been found in igneous rocks in Russia.

Sedimentary rock Wikipedia

Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological ...

Iron Ore Processing for the Blast Furnace

Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.

Minerals, Rocks Rock Forming Processes

Igneous Rocks are formed by the cooling and crystallization of a silicate melt (dominated by oxygen and silicon, with a variety of other metals). The occurrence and distribution of igneous rocks and igneous rocks types can be related to the operation of plate tectonics. The molten rock material from which igneous rocks form is called magma.

Iron Ore: Sedimentary Rock Pictures, Definition More

How Does Iron Ore Form? Nearly all of Earth's major iron ore deposits are in rocks that formed over billion years ago. At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters.

Creating Iron | HowStuffWorks

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

Uses of Iron

Iron is a metallic chemical element that is very common in our planet. It has many uses in different industries and even in the human body. Iron has a chemical symbol of Fe. It is in a category of transition elements and is rarely found in pure form. Iron gets oxidized when it comes in contact with atmospheric oxygen. That’s why most of its ores that you can find in the surface of the earth ...
