Iron Applications
The ores are finely ground to remove unwanted contaminants thus concentrating the iron oxide. The concentrate fines are then agglomerated back into larger particles to enable further processing in blast furnaces. The most common agglomeration technology in the iron ore industry is pelletization with bentonite being the most often used binder.

Iron Ore Sintering: Raw Materials and Granulation
Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and researched in the iron and ...

PROCESS FOR PRODUCING AN IRON ORE FINES …
[0008] Pelletizing is the most recent agglomeration process and was the result of the need to use fine concentrates of magnetite from certain iron ores. Iron ore pellets are produced by agglomeration of particles of less than 45 mm in size, forming pellets of from 8 to 16 mm, in disc or rotating drum. The material to be agglomerated must have a ...

Technology Development for Chromium Ore Agglomeration …
The work discussed a technology for iron ore agglomeration, where a mixed charge was humidified up to 6–10% with a pulp containing bentonite with a particle size of no more than 0.1mm and consumption of 2–18 kg/t. This resulted in an increased impact strength of the obtained agglomerate and its reduced resistance to abrasion.

Review of organic binders for iron ore concentrate agglomeration
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 …
