The production of iron ore pellets can be described as follows: Non-agglomerated iron ores (sinter fines) are mixed together with additives in a ratio that depends on the desired pellet quality and on the quality of the sinter fines.

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...

however, account for over 98 percent of total domestic iron production. 5 The modern blast furnace consists of a refractory-lined steel shaft in which a charge is continuously added to the top through a gas seal. The charge consists primarily of iron ore, sinter, or pellets; coke; and limestone or dolomite. Iron and steel scrap may be added in ...
