iron ore burden is such that the ascending column of g ases interfaces with the maximum surface area of the iron ore - the higher the content of iron ore fines in the feedstock, the lower the permeability of the burden. The iron ore feedstock (pellets and lump ore) is therefore screened to remove fines before being charged to the furnace.

Binders for briquetting. Binders have been used for briquetting coal and charcoal for more than 100 years. Starch came into prominence as a binder for coal and charcoal in the 19th century with the large scale development of briquetting. Use of cement for binding iron and steel plant waste materials is relatively a more recent application.
SNF binders provide greater permeability during firing, leading to higher productivity. Briquetting (roller press or extruder) is used to produce agglomerates with fines materials (up to 5 mm) that need to be put back into metallurgical …
In this study, the various binders, ranging from bentonite, molasses plus hydrated lime and starch were used in the preparation of the briquetting feed. For evaluation of the different binders, the compressive strength of the briquettes was measured.
This research work focuses on the practicality of using organic binders for the briquetting of pellet fines.

Chemical and physical characterization was done for iron ore pellets fines and developed briquettes, as briefly described ...
Fines, dusts, and sludge can be briquetted using a binder to a form that is suitable for charging into the Midrex shaft. To get briquettes with sufficient mechanical strength and thermal stability, a binder is needed.
Sintering consists of granulating moist iron ore fines and other fine materials with solid fuel, normally coke breeze, and loading the granulated mixture onto a permeable travelling grate. Air is drawn downwards through the grate as the temperature is raised. After a short ignition period, external heating of the bed is discontinued and as the solid fuel in the bed burns a narrow …
The cold press briquetting process involves mixing the iron ore pellet fines with a suitable binder, then applying mechanical pressure to form dense briquettes.

Plenty of research has been documented on briquetting of iron ore fines using different binders which include organic binder: lignin liquor, starch, petroleum bitumen, molasses, tar, asphalt, pitch and plastics; and inorganic binder: pyrophyllite, Portland cement, granulated blast furnace slag and sodium silicate solution [11–16].
Cement. Cement is used as a binder for briquetting coal, char, and charcoal and then for briquetting iron and steel wastes.Now cement is widely used in the steel plant as one of the main binders. But use cement will bring gangue and crystal water, so to reduce the cement cost can help to increase the purity of briquette, as cement need a long time to get an ideal strength, …
Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make iron ore concentrate …
