Dec 28, 2015  These ores are the original material from which high grade Mesabi hematites have been evolved by natural leaching and oxidation. 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.

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 ...
