Carboxylmethyl cellulose (CMC) has become a commercial organic binder in agglomeration of iron ore concentrates. The relative molecular mass and degree of substitution (DS) of CMC have a large impact on its binding performance. The interaction mechanism between CMC and iron ore particles was analyzed through Zeta potential …

The majority of iron ores must be ground to a fine particle size to allow the iron oxides they contain to be concentrated, and the concentrate must then be agglomerated back into large enough particles that they can be processed in blast furnaces. The most common agglomeration technique is pelletization, which requires the use of …

DRI steelmaking requires a higher grade of iron ore than blast furnaces, the dominant global technology. DR-grade iron oreideally has an iron (Fe) content of 67%or more and such deposits are scarce --only a small percentage of global seaborne iron ore comes close to DR-grade.

World iron ore production doubled from 2003 to 2010 to reach 2.6 Bt to mainly satisfy the colossal demand from Chinese steel mills for iron ores. The decrease in ore quality, the development of iron ore deposits with new iron ore types, the vast volume of ore mined and the increased requirements from steel makers have created an ever greater ...

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.

Iron Ore Agglomeration Technologies. Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore.

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."
