Main advantages of iron ore briquettes. Lower CO2 emissions. Briquettes emit less carbon dioxide than traditional agglomeration processes (pelletizing and sintering). It can reduce CO2 emissions in the steelmaking chain by up to 10%. Lower gas emissions. Iron ore briquettes reduce emissions gases such as sulfur dioxide and nitrogen oxide.

Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson (Yamaguchi et al., 2010). The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, …
Agglomeration processes combine small, discrete particles into larger aggregates, where the individual particles are still discernible (Ennis and Litster 1997). During iron ore agglomeration or pelletization, moist iron concentrate particles and flux materials are rolled into balls with the aid of a binder (Figure 1).

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.
