Coke
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

primary processes of iron ore
The only source of primary iron is iron ore. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3).
Iron processing | Britannica
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron …
What Are the Main Uses of Iron Ore? | Reference.com
Iron ore is used primarily in the production of iron. Iron is used in the manufacturing of steel. Steel is the most used metal in the world by tonnage and purpose. It is used in automobiles, airplanes, beams used in the construction of buildings and thousands of other items.
How Iron and Steel Work - Iron Ore | HowStuffWorks
Carbon and carbon monoxide combine with the oxygen in the iron ore and carry it away, leaving iron metal. In a bloomery, the fire doesnt get hot enough to melt the iron completely. Instead, the iron heats up into a spongy mass containing iron and silicates from the ore.
From ore to steel – ArcelorMittal
The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or …
Low grade Iron Ore Beneficiation and the Process of ...
Sep 25, 2018 · The crushing, grinding and screening system for the beneficiation of the iron ore is to be designed taking into account the requirements of the downstream beneficiation processes. The crushing units may include primary, secondary, tertiary and quaternary crushing units. Jaw, gyratory, cone, and roll crushers are used for ore crushing.
Steel - Primary steelmaking | Britannica
Of the three major steelmaking processes—basic oxygen, open hearth, and electric arc—the first two, with few exceptions, use liquid blast-furnace iron and scrap as raw material and the latter uses a solid charge of scrap and DRI.
Steelmaking - Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen , silicon , phosphorus , sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese , nickel , chromium , carbon and vanadium are added to produce different grades of steel .
Steps in the Modern Steelmaking Process
Jan 14, 2020 · Two processes, basic oxygen steelmaking (BOS) and electric arc furnaces (EAF), account for virtually all steel production. Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace.
(PDF) Life cycle assessment of iron ore mining and processing
Many minerals contain iron, but the primary sources of iron ore minerals used to make iron and steel are hematite, magnetite, goethite, siderite, and pyrite.
