Iron ore is mined in around 50 countries – the largest producers are Australia, Brazil and China. Around 98% of iron ore is used in steelmaking. During the ironmaking process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities).
Processes of Ore Formation Current theories of the genesis of ore deposit can be divided into internal (endogene) and external (exogene) or surface processes. It must be understood that more than one mechanism may be responsible for the formation of an ore body.
The Iron Ore Process Flowsheet. The iron ore beneficiation flowsheet presented is typical of the large tonnage magnetic taconite operations. Multiparallel circuits are necessary, but for purposes of illustration and description a single circuit is shown and described.
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.

Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red.
Iron ore concentrate (known as "filter cake") provides the ingredient for the mine’s final product, but it must be put in a form which is suitable for shipping and for handling in the blast furnace.

Ore smelting. In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed.
The disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry cake which is sent for pelletizing. This process allows ore of very low magnetite content to be processed into a high quality product.

Smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke.
Jan 01, 2012· The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization:. The binder makes the moist ore plastic, so that it will nucleate seeds that grow at a ...
The process is called “carbonization” or “Destructive distillation of coal”. Coal consists of complex organic compounds in which C,H,N,O, and S atoms are bonded together.
Description. The Disc Filters belong to the side feed group and have been around for many years. They are generally used in heavy duty applications such as the dewatering of iron ore taconite, hematite, coal, aluminum hydrate, copper concentrate, pyrite flotation concentrates and other beneficiation processes.
The flexibility of the sintering process permits conversion of a variety of materials, including iron ore fines, captured dusts, ore concentrates, and other ironbearing materials of small particle size (, mill scale) into a clinkerlike agglomerate.

The ore part of a charge consists of iron ores and concentrates, manganese ores and various types of scrap containing iron. These ore parts are usually contained in a charge as
Oxidation Filtration (Iron Removal) Oxidation/filtration refers to precipitative processes that are designed to remove naturally occurring iron and manganese from water. The processes involve the oxidation of the soluble forms of iron and manganese to their insoluble forms and then removal by filtration.
passes it through a filter paper, and runs an iron test on the clean, filtered water (filtrate). If no iron is present, it has all been oxidized and is being removed in the filtration process.
Over time, the softener ceases to function effectively on either iron or hardness. At higher pH levels the softener will be ineffective. At low pH levels it is hard to precipitate iron from water. ... Oxidation Additives Plus Filtration For Well Water Iron Removal: ... Pyrolusite is a natural ore that oxidizes and then filters the resulting ...
Iron ore often has silicon dioxide (sand) impurity which must be removed during the process. To do this limestone is added to the charge. The limestone (chemically, calcium carbonate) decomposes in the heat of the furnace to calcium oxide.
Process overview. Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process.
