The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter …
We are a leading North American producer and exporter of premium iron ore pellets and high-grade concentrate.

ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet. Meeting these requirements leads to the formation of strong …
Brazil is the second-largest producer of iron ore and pellets in the World. In 2014, 411.8 Mt of iron ore and 54.7 Mt of pellets were produced. Main producers are the states of Minas Gerais (68.4%)...
The constant demand for iron ore leads to the need to mine even low-grade deposits. The diminished quality of natural resources is countered by economic, ecological, and technological restrictions that require the processing of the extracted iron ore. An enrichment of iron ore can be achieved by separating unwanted components. This enrichment ...

Iron grades of Iron ores A and B were 68.20% and 69.32%, respectively. SiO 2 content of Iron ore B was less than 2.0%. The particle sizes of Iron ores A and B were small with percentages of −200 meshes less than 80%. Iron ore A had a better pelletizing performance than Iron ore B from the production practice.
1 – INTRODUCTION Pelletizing has been producing pellets for blast furnaces and direct reduction use, since the 1950's. It started taking advantage of low grade taconite, a magnetite ore, in ...
In the last years, pelletizing has been playing an important role for iron ore mining and ironmaking. Some factors have contributed to this fact like as: depletion of high-grade iron ore reserves ...
This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron ...

As greater amounts of fine iron ore concentrates enter the marketplace, new investments in iron ore pelletizing capacity are inevitable to deliver these concentrates to steel industry consumers.
Pelletizing Indexes. The evaluation indexes of pelletizing quality include total iron grade (TFe), drum strength, abrasion resistance index, compressive strength, reduction degree index (RI) [], reduction expansion index (RSI), low temperature reduction pulverization rate and bursting temperature.In this paper, the quality of raw ball is evaluated by the compressive …
Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes.
