The Assay Guide to Iron Ore
What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron …

Iron processing
Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron …
Optimisation model of fuel distribution in materials bed of iron ore …
In this study, the optimisation model of fuel distribution base on numerical simulation was proposed to reduce the fuel consumption of sintering process. The simulation model of sintering process was carried out according to the heat and mass transfer, and the physical and chemical reactions of sintering.

Iron processing
Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …
Beneficiation of Fine Iron Ores using the Desand Process
The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine …

This kind of iron is called Cast Iron and has a slightly lower carbon content 2 – 3 %. This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts ...
Iron Ore Smelting Process
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off …
