Iron Ore Pelletizing Process: An Overview IntechOpen
Jul 11, 2018Pellets are obtained by adding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [ 6, 8 ]. This cohesive tension of fine particles due to water is called neutral tension.

Sintering: A Step Between Mining Iron Ore and Steelmaking
Jun 11, 2019The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption.
