The LMP process is a lower temperature iron ore agglomeration method designed to operate at about 300°C lower temperatures than existing iron ore pelletising processes, while maintaining the required physical and metallurgical agglomerate properties. The novelty of the LMP process is characterised by the lower
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 …
The work discussed a technology for iron ore agglomeration, where a mixed charge was humidified up to 6–10% with a pulp containing bentonite with a particle size of no more than 0.1mm and consumption of 2–18 kg/t. This resulted in an increased impact strength of the obtained agglomerate and its reduced resistance to abrasion.
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 begins with a discussion of raw materials preparation and the beneficiation process.
Virtually all of the 62 million metric tons of iron ore produced for the US iron and steel industry during 1998 was pelletized (Kirk, 1999). Eight of the nine plants in the US utilized bentonite clay as a binder, while the ninth plant used an organic binder.
Agglomeration of Iron Ores covers in considerable detail both the sintering and pelletising of iron ore fines and concentrates that are generated along with lump ore in iron ore mines around the world, either naturally or after upgrading in a …
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify the key steps of the process, that is, granulation and thermal densification. Discussion is then focused on the effect of the chemical, physical, and ...

Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and researched in the iron and ...
Hence, an agglomeration technique should be applied to fine concentrate. The most commonly employed one is pelletizing in iron ore industry. In pelletizing, iron ore, water and a binder are balled in a mechanical disc or drum to produce agglomerates. Bentonite is …

In order to increase agglomeration production and improve its quality while reducing energy consumption, a new intelligent blending method has been established at Ansteel to optimize its sinter blends. The statistical model of the ore blending results shows that (1) a blending ratio of 47.2% Ore A and 52.8% Ore C corresponded to the best sinter yield of …
Pelletizing iron ore fines is an agglomeration process that through a thermal treatment converts the ultra-fines fraction thereof into small balls ranging in size from 8mm (0.31 in.) to 18mm (0.71 in.), with adequate characteristics for feeding steel reduction works. The binder more used to make pellets is bentonite, which is an item of ...
