Binder is essential for producing iron ore pellets and enabling them to survive handling, drying and roasting. Presently, bentonite is chosen as a worldwide binder in the iron ore pelletizing process [1], [2], [3].
Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.

Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive
At present, the grade of iron ore powder in china is generally low, and iron concentrates are heavily dependent on foreign imports. At the same time, adding a large amount of bentonite in the pelletizing process reduces the iron grade, deteriorates the pellet performance, and increases the smelting cost.
Organic binder is a significant substitution of the bentonite in iron ore pelletizing process, reducing the exploitation of clay resource and improving the quality of pellets.
A brief introduction to recent developments in iron ore pelletizing is provided in this chapter, including the world output of fired pellets, pellet production processes, preparation of pellet feed, inorganic and organic binders, and new additives. Throughout the chapter, the authors have used a difficult pellet feed, that is, a Brazilian specular …
They allow the iron to be directly reduced into lumps or balls. Such pellets are usually lighter because oxygen has been removed from the ore at the start of the process. Iron ore pelletizing progress The iron ore pelletizing process mainly includes preprocessing (preparation of high-quality iron fines), mixing (preparation of raw …

The iron ore pelletizing process mainly includes preprocessing (preparation of high-quality iron fines), mixing (preparation of raw materials), and pelletizing (balling).
Optimal plant performance and lowest TCO (Total Cost of Ownership) Produces pellets with excellent metallurgical and physical properties for both the blast furnace and the …
The traveling grate indurating process is responsible for two-thirds of the world's installed pelletizing capacity. Outotec offers the industry's leading induration technology for iron ore pellet processing, which is based on over 60 years of experience and world-class R&D. This process produces pellets with excellent physical
The process of iron oxide pelletizing includes three principal stages: the preparation of raw material, the formation of green pellets …
Currently, coal is one of the main inputs of pelletizing iron ore. Wendling [2] showed that the addition of coal in pellets began in the 1990s, with the Gulf War and the oil crisis, and found several advantages for the usage of …
Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …
The various steps of occupational health assessment of hazardous process in an iron ore pelletizing industry are as follows: Process description The concentrate slurry is received at pellet plant and stored in slurry tanks [ Figure 5 ].
The iron and steel industry in China is suffering from the burden of overcapacity, structural adjustment and upgrading. In order to analyse and improve the energy efficiency, the life cycle energy consumption and greenhouse gas (GHG) emissions of iron pelletizing are estimated in this work.
Keywords: iron ore, pelletizing process, binder, bonding mechanism, induration technology 1. Introduction Iron ore and iron ore pellets are important sources of iron for manufacturing steel. The ...
This paper summarizes more than a decade of systematic studies of the flow field in an iron ore pelletizing rotary kiln using computational fluid dynamics (CFD) on simplified models of a real kiln. Physical, laser-based experiments have been performed to validate part of the numerical results. The objective is a better understanding of the kiln …
The NOx reduction in the iron ore pelletizing process becomes an important environmental concern owing to its role in the formation of photochemical smog and acid rain. Thus, it is essential to develop new technologies for reducing NOx emissions in order to contribute to the cleaner production of pellets. In this paper, NOx reduction by …
Another type of ore found in this country is the itabirites that have lower iron contents. Beneficiation and concentration steps are required to prepare these materials for the pelletizing process. A general view of Brazilian types of iron ores, mines, and mining companies is given in this work.
Iron ore is the most critical mineral resource for any Iron and Steel Industry. Know about the Applications of Iron Ore Pellets & Iron ore Pelletization Process.
Pelletization refers to the process of converting iron ore fines into agglomerates by mixing them with a binder and water to produce pellets, which are then dried and heated to become hard enough for storage and handling. ... In order to omit the pelletizing process, highly advanced catalyst technology must be applied to generate …
Moisture content (MC) is an important quality metric of iron ore green pellets in pelletizing process in ironmaking industry. Current image-based methods for MC estimation may result in big errors for gray-scale pellet images captured under various lighting conditions. We proposed a simple image-based method to improve the MC …
