Iron Ore Pellets and Pelletization Process – IspatGuru
Nov 26, 2014· Studies of green pellets and induration of magnetite and high grade hematite iron ore fines with low alumina have been carried out in different parts of the world. But the results of these studies cannot be directly interpreted to iron ores with higher amount of alumina (Al2O3) due to the difference in chemistry and mineralogy.

Understanding Reactions in Iron Ore Pellets
The induration furnace for iron ore pellets was originally designed to process concentrates with high contents of magnetite. To support the use of haematite concentrates, internal fuel was added to the pellets in the form of ground coke breeze or anthracite. To ensure that the addition of coke breeze was not excessive, the heat of magnetite equivalent' or heat of magnetite equivalent (HME ...

The Lake Superior & Ishpeming Railroad (LS&I), contrary to what has been widely published, does not haul "taconite" pellets, but what are properly referred to as "processed iron ore" pellets. Magnetic taconite ore, extensively mined on the Mesabi Range of Minnesota, is not found in appreciable quantities on the Marquette Range.
Understanding the high-grade iron ore market
There are two main technologies for converting iron ore (iron oxide) into metallic iron: the blast furnace (BF), which is by far the most common, and the direct-reduction (DR) route, which accounts for just over 100 million tonnes per year (tpy), or around 8% of global primary iron production. Blast furnaces are usually paired with basic oxygen furnaces (BOFs) to convert the hot metal or pig iron they produce …
Mechanisms in oxidation and sintering of magnetite iron ...
Thermal volume changes and oxidation mechanisms in magnetite iron ore green pellets balled with 0.5% bentonite binder, as a function of raw material fineness and pellet porosity, are shown. When a pellet starts to oxidize, a shell of hematite is formed around the pellet while the core still is magnetite.
Iron ore pelletizing - Outotec
Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help ...

iron processing - Ores | Britannica
iron processing - iron processing - Ores: 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 iron ores consist mainly of hematite (Fe2O3), which is ...
