The need for agglomeration arose initially from the utilization of lean-grade ores and slimes. However, with the technological development, the usage of agglomerates in iron making has become imperative for its profitability. The agglomeration processes, supported by research and development have undergone substantial improvement in recent years.
Iron ore agglomeration is a wet process, where particles are held together by the surface tension and capillary forces when wet, they will fall apart upon drying unless binders are present.
The briquette, which is produced through the low-temperature agglomeration of high-quality iron-ore, could be used to replace sinters, pellets and granules in steelmaking, cutting greenhouse gas ...

Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The 'recipe' for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests

He has over 38 years research experience in iron ore beneficiation and agglomeration in India, working for various iron and steel companies and research organisations, including the Steel Authority of India (SAIL) in Ranchi, the Indian ...
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 …

In 1970s, to ameliorate the undesirable leaching condition and obtain better extraction efficiency, the agglomeration and its processing controls were firstly mentioned in …
This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book …
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.

Ram Pravesh Bhagat (born October 1954 has 36 years of research experience in the iron ore beneficiation & agglomeration areas while serving premier R&D establishments, SAIL-RDCIS and CSIR-NML. He has worked with Soviet Experts to implement R&D Projects at SAIL plants aimed to improve the productivity of sinter and its quality. In the 1990's ...
In the last decade, several concentrated solar power (CSP) plants have been installed worldwide with over 300 MW capacity. New developments in the solar receiver systems and heat engines are constantly being carried out for CSP technologies. Recent work by Pye et al. suggests that an average thermal efficiency of over 97 % is possible to achieve using a tubular cavity receiver …
Figure 1 Green-ball growth during iron ore agglomeration. Individual iron ore particles are wetted, and pellet 'seeds' are nucleated. During agitation in the rotating drum or disc, small seeds can grow by consolidation of individual granules and layering of new feed material (Iveson et al 2001).
