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.

Selective agglomeration is used to detach the iron ore from apatite through all the beneficiation stages. The initial Fe content was 54.6% and P 0.39%, which resulted in producing a concentrate of 65.9% Fe, P < 0.02%, and SiO 2 = 5.3%. Figure 2 shows the removal of phosphorous through a selective agglomeration process .
