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 …

Abstract. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Owing to the depleting reserves of traditional high grade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia.

The iron ore fines and concentrate cannot be directly utilized in blast furnace, and therefore, its agglomeration i.e. enlargement of particle size is necessary before it is used as feed for iron making. Sintering is one of the methods of agglomeration. All iron oxide bearing wastes and coke breeze is used for sintering purpose. The use of ...

The most common agglomeration technique is pelletization, which requires the use of binders to hold the iron oxide grains together so that the agglomerates can be sintered into high-strength pellets. Although bentonite clay is the most commonly used binder, there are many other possibilities that could be competitive in a number of situations.

A novel iron ore agglomeration process using concentrated solar flux, called a solar-based LMP process is proposed. The process has been tested using laboratory experiments inside a hybrid solar simulator reactor setup. The results indicate no change in the reaction mechanism of LMP formation under solar irradiation compared to electrical heating.
