Iron ore pelletizing 3 Process flexibility There are two main processes for producing iron ore pellets: The Grate-Kiln system and the straight grate system. In the straight grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones. Any change in one section effects the residence
Iron Ore Sintering and Pelletizing Capabilities The Natural Resources Research Institute's Coleraine Minerals Research Lab is a full service minerals research laboratory with complete capabilities for sintering and pelletizing iron ore on both bench and pilot scale.
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.
In pelletizing, iron ore, water and a binder are balled in a mechanical disc or drum to produce wet pellets. Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of its acid constituents (SiO2 and Al2O3
Platts Iron Ore Index, or IODEX (IODBZ00), is a benchmark assessment of the spot price of physical iron ore. The assessment is based on a standard specification of iron ore fines with 62% iron, 2.25% alumina, 4% silica and 0.09% phosphorus, among other gangue elements.
A review of binders in iron ore pelletization. The most common agglomeration technique is pelletization, which requires the use of binders to hold the iron oxide grains together so that the agglomerates can be sintered into high-strength pellets. Although bentonite clay is the most commonly used binder, there are many other possibilities
key physical properties are size consist, mechanical strength: economic importance. (a) yield of pellet, lump ore converted to DRI (b) performance of the shaft reduction furnace unlike blast furnace, pellets (and lump ore) are only solid materials and so determine gas
Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick
that are charged into a blast furnace include lump ore, sintered ore and pellets. The ones charged into an EAF include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The
The iron ore concentrates subjected to pelletizing tests represent four different Canadian sources. Extensive test work was carried out on three samples from the Adams Mine near Kirkland Lake, Ontario. The major proportion of the equipment used in batch balling and pellet evaluation is quite common to most well equipped mineral dressing laboratories.
Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the formation of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.

Heating Iron Ore Slurry to Improve Filtering Efficiency Prior to Pelletizing . Robert E Wood . Inproheat Industries Ltd. Wesley Young, P. Eng . Inproheat Industries Ltd. Abstract . Engineers have known for some time that the efficiency of filtering iron ore concentrate slurry can be
Iron Ore Pelletizing Bentonite The need for iron ore pellets is directly connected to the steel production industry. Through the pelletizing process, iron ore fines are converted into spherical pellets, which are then suitable as feed material in blast furnaces for pig iron production.
Apr 21, 2014Iron ore pellets are marble-sized balls of iron ore that are fused with clay for transportation, and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from a low-grade iron ore involves processes like mining, crushing, separating, concentrating, mixing, pelletizing, and shipping.
Outotec awarded a large iron ore pelletizing plant and filter press order from India. Outotec has signed a contract with an Indian customer for the delivery of an iron ore pelletizing plant and filters for the expansion of their existing operations. The order value exceeds EUR 50 million and is booked in Outotec's 2018 first quarter order intake.
The pellets form of iron ore. Iron ore pellets can be used as a substitute to sinter and calibrated lump ores in the blast furnace burden. Apart from these pellets can be applied to some non-ferrous metal ores such as lead and chromium ores [ 11 ].
The Symposium on Iron Ore Pelletizing focuses on the topics such as feed preparation covering grinding, flotation and filtration, balling, including new binders, additives, covering conventional and alternative source, induration, including machine design and alternative energy sources, and
Pelletizing iron ore. The equipment used to pelletize iron ore needs to be capable of conveying, feeding, mixing and screening a wide range of materials under the toughest conditions. High handling speeds and high plant availability are both essential. Here, Schenck Process solutions make a vital contribution to ensuring consistent quality and optimizing the production process.
An indurated iron ore pellet having unusually high crushing strength and comprising a core portion composed of particles of iron ore and a casing of refractory material covering the core and bonded thereto, said pellet having properties and characteristics obtainable by forming a ball-like body of moist iron ore fines, rolling this body in contact with comminuted refractory material having a melting point
System engineers at an iron ore pelletizing plant in the Middle East needed to augment the functionality of their plant's DCS. Although the DCS was furnished by a major supplier, there were certain specific requirements for a project that its built-in features could not meet.
Pelletizing. In the pelletizing plant, pellets are produced from the iron ore concentrate from the concentration plant. The pellets are dried, sintered and cooled before they are ready to be transported to the ports. LKAB has six pelletizing plants: three in Kiruna, two in Malmberget and one in Svappavaara.
Iron ore pellet feed fines (PFF) The iron ore pelletizing process is marked by spherical pellets in a nar-row grain size distribution ranging between 9 mm and 15 mm. The raw material in the process consists of iron ore ( 100 μm), binders (i.e. ben-tonite) and additives such as coal dust. The moisture of the raw mate-rial can be variable.
Iron ore pelletization is a two step process consisting of pellet production in balling circuits and pellet induration in straight-grate or grate-kiln systems. Extensive applied research and plant scale testing have been directed to understanding and improving the induration process and pellet quality.
Iron ore pellets and Pelletizing processes Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer
Welcome. It is an honour and a pleasure to be the Honorary Chairman of this 4th Symposium on Iron Ore Pelletizing organized by COREM in the beautiful Quebec City. Having organized the 1st Symposium in 2003 when working at COREM, it particularly touches my heart to see this event becoming a tradition in the pelletizing world.
Iron mineral pelletizing is part of the work done at specialized mine plants to generate a product that can be used as feed in blast furnaces or at direct reduction plants. Iron mineral pelletizing results in better performance in blast furnaces by facilitating the circulation of air and gases between the different components of the blast furnace charge.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is more integral to the global economy than any other commodity, except perhaps oil.
