Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon ...

· Manufacturers distinguish between high and low grade ores that contain different impurities mixed with the iron and determine the end uses of iron ore. Iron is often used to make permanent magnets. When sites with iron ore are identified, engineers and geologists study the rock to learn more about the specific type and determine the potential yield from the mine.
WhatsAppعرض المزيد· Iron ore is any rock or mineral from which iron can economically be extracted. It comes in a variety of colors, including dark gray, bright yellow, deep purple, and rusty red. The iron comes in the form of iron oxides such as magnetite, hematite, limonite, goethite, or viable forms of ore contain between 25% and 60% iron.

Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron compound from which iron can be smelted commercially. This term is customarily restricted to hard coarsely banded, nonbanded, and noncherty sedimentary rocks of postPrecambrian age.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Definitions A crosssection of the earth showing its different layers. The inner core is the innermost layer of the Earth, and is believed to be a solid ball composed of iron and nickel along with some light elements (, oxygen, sulfur, silicon). It has an estimated radius of 1220 km (768 mi). Seismologist Inge Lehmann was the first to discover the inner core as being solid and covered by a ...

Iron ore is rock which metallic iron can be extracted from. Iron ore is the most common element in the world and makes up close to 5% of the Earth''s crust. This makes it one of the most abundant rock elements. Iron ore that contains a high quality of hematite or magnetite are known as "natural ore" and they can be entered directly into blast furnaces that produce iron.
