The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron (III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace.
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 and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery
blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2"). Pellets are screened to meet the size specification ...

The process of mining low -grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required. The equipment used includes diamond -bit rotary drills, hydraulic shovels and loaders, water wagons, production trucks and heavy-duty conveyors.
Development of the Process for Obtaining Iron-Ore Pellets with Required Metallurgical Properties ... that at heating rates and temperatures found in industrial units the roasted pellets that are not oxidized to a full extent and are characterized by zonal structure do not meet the requirements imposed for the blast-furnace smelting raw materials. To develop a process that would ensure high ...
Blast furnaces are so hot that they melt the iron, which is drained off and poured into moulds to form bars, called ingots. The production of iron involves the use of iron ore, limestone, and coke.
The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source - as you will see below.

The process of extracting the metals from their ores and refining them is calledmetallurgy. The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore.

The aluminothermic process can also be carried out in a refractory-lined steel pot or water-cooled copper crucible. A charge of V 2 O 5, iron oxide, and aluminum is ignited with a barium-peroxide fuse or a magnesium ribbon.
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing ...
Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.

21/06/2016 Steel making is the method of processing and producing steel from iron ore and scrap. It focuses on removing the slugs and other unwanted materials like phosphorus, sulphur, silicon, nitrogen, and excess carbon from the raw iron. The next step targets on alloying it by adding various elements like manganese, chromium, nickel, and vanadium.
