Made from metallurgical wastes (sludge and top dust) and iron-ore fines, the extrusion briquettes (brex) are a new component of the blast …
Characterization of modified humic substances based binders for iron ore agglomeration was examined by chemical analysis, optical density, Fourier transform infrared spectrum (FTIR), and thermogravimetry and differential scanning calorimetry (TG–DSC). Chemical analysis displays the proportion of fulvic acid (FA) to humic acid (HA) in the binder is …
Projects supported by the Iron and Steel R&D Funding Round seek to accelerate novel and innovative low emissions iron and steel technologies using Australian iron ore. Ongoing decarbonisation initiatives in the steelmaking industry necessitate high-grade (iron > 66%) ironmaking feedstocks, which are heavily impacting Australia's iron …
Announced in 2021, these iron ore briquettes began to be developed by us around 20 years ago at our Ferrous Metals Technology Center in Nova Lima, Minas Gerais. They are the latest in a long line of iron ore products we have offered over the course of our history, resulting from major investments in research and innovation.
Agglomeration binder is the binder used for agglomeration in mineral processing. During mineral processing, usually an external force is applied to consolidate powder ore with the help of agglomeration binder, so that the mineral pellet will have the desired shape, particle size, mechanical strength, and roasting properties, in order to …
This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and …
FEECO Balling Drum. Balling drums consist of a large, cylindrical "drum," through which the material tumbles to promote agglomeration. Much like the disc pelletizer, binder and feedstock are continuously added and …

In this Special Issue, we welcome the reviews and research articles in, but not limited to, the following areas. Iron ore characteristics and their impacts on the final agglomerates' quality and process …
Amongst various processes used in agglomeration, sintering and pelletization are widely used in the iron ore industries. About 70% of the blast furnace feed is reporting from the sintering processes. The objective of iron ore agglomeration is to generate a suitable product of granules in terms of thermal, mechanical, physical, and …
Product emits about 80% less CO2 in its manufacture in relation to pellets, contributing to reduce emissions of scopes 1 and 2 of the company ... the briquette is produced from the agglomeration at low temperatures of iron ore using a technological solution of binders, which gives the final product high mechanical strength. ... in line …
The LMPs of stoichiometric (1 mol Fe 3 O 4 and 1 mol CaCO 3) and half-stoichiometric (1 mol Fe 3 O 4 and ½ mole CaCO 3) compositions were prepared using laboratory grade chemicals (98 wt % pure Fe 3 O 4 and 99.5 wt % pure CaCO 3 with average particle size of 5 μm), following the procedure outlined by Purohit et al. (2020a, …
Sintering is a process that consists in the thermal agglomeration of a mixture of fines that comprise iron ore, recycled iron and steelmaking products, slag-forming elements, and solid combustible (coke). The process has as objective obtaining a charge with the suitable physical–chemical and mechanical properties to be fed into the blast ...
FEECO Balling Drum. Balling drums consist of a large, cylindrical "drum," through which the material tumbles to promote agglomeration. Much like the disc pelletizer, binder and feedstock are continuously added and particles pick up additional fines as they tumble through the drum, which is set on a slight angle to allow gravity to assist in moving …
The iron concentrate is a product of the hydrometallurgical processing of uranium ore. As it contains up to 65% of iron, it can be used as a raw material for ferrous metallurgy (Fernández ...
Iron ore agglomeration is a wet process, where particles are held together by the surface tension and capillary forces when wet, they will fall apart upon drying unless binders are present.
Our heavy-duty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.

Primetals Technologies' comprehensive technological expertise on the entire metallurgical process chain is the …
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 …

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 ...
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.
