Organic binders for iron ore pelletization and

Dec 01, 1995· These totally synthetic binders are used in conjunction with limestone. The benefits of organic binders are: improved metallurgical parameters of the fired pellet, especially the reducibility, which results in more efficient use of gases in the blast furnace; reduced silica in the pellet, in the case of Eveleth Mines this was a reduction of 0.5%, a lower silica pellet reduces slag in the blast furnace;

Effect of adding limestone on the metallurgical

Aug 10, 2015· One of the most common fluxing materials for iron ore pellet production is limestone, which is mainly calcium oxide (CaO). In this study, the effect of adding limestone on the metallurgical properties (reducibility, swelling, cracking, softening temperature, Low-Temperature Disintegration, Cold Crushing Strength) of acid iron ore pellets was investigated using a comprehensive set ofCited by: 28

pellets more competitively, using organic binders for agglomerating iron ore. The goals of this research were (1) to determine the physical and metallurgical pellet properties of pellets made with different types and dosages of organic binders and (2) to relate these pellet properties to the binder properties.Cited by: 24

Effect of limestone and dolomite flux on the quality of ...

Feb 01, 2021· For the preparation of pellet feed material, the goethetic-hematite iron ore fines were thoroughly mixed with the additives: limestone, dolomite, and anthracite coal as per the plan of experiment. It should be noted that in the pelletization of goethetic-hematite ore, there is no need to use any binding material as the ore itself acts as a self-binder due to the presence of kaolinite mineral.Cited by: 2

WO2009109024A1 - Binder composition for pelletizing

The present invention refers to a binding composition containing bentonite for use in binding finely ground iron ore. The composition of the invention comprises bentonite and molasses. The...Cited by: 8

Utilization of Lime Fines as an Effective Binder as well ...

19/06/2015· A laboratory study was carried out to characterize the physical, chemical and mechanical properties of lime fluxed (varying basicity 0–2) hematite iron ore pellets. Lime was used as additive as well as fluxing agent for making iron ore pellets. The effect of additives on different properties of pellets was studied. The findings show that on increasing the addition of lime, more of calcium ...

High-carbon fly-ash as a binder for iron ore pellets ...

01/09/1999· During production, dried iron-ore pellets are required to have crushing strength of at least 22.2 newtons (5 pounds force) per 12.7 mm (1/2 inch) diameter pellet. The pellets are then sintered at temperatures up to 1300 C and must not exhibit a significant degree of spalling or cracking.

Processed of Sand Ore Iron Oxide Ferro Low as Raw Steel in ...

Iron ore pellet raw material consists of a main ingredient; iron sand, activated carbon, limestone, and a binder; bentonite, drops, feces. Furthermore, raw iron ore pellets in a furnace reverberatory fuel LPG and coke at 1400oC temperature for five hours agglomeration process occurs.

Steel Pellets, Iron Ore Pellets for Sale | Huaro Steel

Pellets are small balls of iron ore used in steel production. They are one of the important sources of iron in the manufacture of steel. Pellet production is the basis of the steel production process. Steel pellets are made from iron ore powder with additives such as limestone, dolomite, olivine and binder bentonite.

Iron Oxide Pellets - 911 Metallurgist

20/10/2017· Details of the pellet binder research are available in Bureau Report of Investigations (RI) 9230, “Effectiveness of Organic Binders for Iron Ore Pelletization,” and RI 9257 “Utilization of Papermill Sludges as Binders for Iron Ore Concentrate.”


The use of conventional bentonite binder is favorable in terms of mechanical and metallurgical pellet properties, however, because of its acid constituents bentonite is considered as impurity especially for iron ores with high acidic content.

Iron Ore Pellets and Pelletization Process – IspatGuru

26/11/2014· Slurry tank for storage of concentrated iron ore slurry from beneficiation plant. The particle size of iron ore in the ore slurry is less than 45 micro meter for around 80 % of the particles. Additive materials (such as dolomite, limestone, lime or olivine etc. depending on the quality of the pellet to be produced) is added to the slurry.

Effect of molasses binder on the physical and mechanical ...

05/01/2019· Molasses was used as an alternative binder to the bentonite binder. The change in moisture absorption by pellets prepared with different iron ores and different molasses contents were investigated. Iron ore properties exerted the major effect on pellet behavior and final pellet quality. The absorbed moisture content of pellets prepared without binder, bentonite-added pellets, and molasses ...
