Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of environmentally harmful dust and gases during the production process [1], [2], [3].The two primary raw materials for pellet production are hematite and magnetite concentrates.

The recoverable iron mineral is finely disseminated magnetite and the ore must be ground to about 80 % of size – 325 mesh for liberation, the concentrate containing about 65 % iron and 8 % silica. By 1945 research and development at the Station had made considerable progress.

metallic iron from ore directly, in a single step. A particularly promising approach is the iron nugget process, where pellets are made that consist of iron oxide concentrate, powdered coal, flux, and a binder. When these pellets are heated, they self-reduce to form metallic iron droplets that separate from the slag.

Agglomeration of Iron Ores Bi Xuegong1 and Xu Kuangdi2 1School of Materials and Metallurgy, Wuhan University of Science and Technology, Wuhan, China 2Chinese Academy of Engineering, Beijing, China Agglomeration of iron ores is the iron ore pre-treatment process in which the powdery iron ore that cannot be directly fed into a blast furnace

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 iron ore concentrate pellets, but it is …
