iron ore, it seems likely that the great majority of output will be blast furnace-grade. Vale forecasts that, although there will be a shift towards higher quality iron ore over the rest of this decade, there will be no change in the proportion of seaborne iron ore supply over 66% Fe by 2030, remaining at just 3% of the total as it was in 2020.
Iron ore pelletizing, or balling, is the process of transforming fines into spherical granules anywhere from 8 – 16mm in size via tumble-growth (agitation) agglomeration using either a disc pelletizer (pan granulator) or rotary drum.
The purpose of the iron pelletizing process is to convert the iron-rich fine-grained minerals into blast furnace charging material, which is defined as pellet, through agglomeration and hardening. The pellets are rigid and generally spherical shape and must have the following properties to be used in the high-temperature furnace:
Discussed below are the different binders and additives used in the industry and the stages of pelletizing (mixing, pelletizing, indurating). The textbook by Meyer ... Besides iron ore agglomeration, these pelletizers can also be used for other materials such as copper ore, gold ore, coal, and fertilizer [12].
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 …
