Adapting to Raw Materials Challenges: Part 1
Cost of beneficiation. Upgrading run of mine iron ore to DRgrade is expensive. Note: DRI manufacturers have been pushing for higher quality DRgrade pellets. Additional energy and investment costs for beneficiation technology. Higher yield losses associated with increased beneficiation. Supply Restriction. High quality ore is more difficult to reach; DRgrade raw material monopolized by ...

Investigation on the Reducibility of Agbaja Iron Ore Lumps
Agbaja iron ores: The Agbaja iron ore lumps are in sizes or in fines. Production/availability of lumps is limited by virtue of the natural occurrence and because of generation of lot of fines during crushing of large lumps present in the runoff mines (ROM). Iron ore with very lowgrade iron ore are not suitable for operating the metallurgical plants. The very low grade ores are upgraded to ...

Understanding the highgrade iron ore market
Iron ores can be formed of several different minerals; the most common are hematite and magnetite. DSOs, including the midgrade products Rio Tinto and BHP produce from Australia's Pilbara region and the highgrade 65% Fe fines Vale produces in Brazil, are predominantly hematite products.

Iron ore (fines)
Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3). Ores ...

Iron Ore
Historically it has provided a direct feed to smelters either as a raw lump or fines, also in a processed form such as sinter or pellets. There are emerging markets for new varieties of feedstock. Examples include sintered iron carbide and 'DRI' ore, which is natural ore with Fe >69% and low levels of specific trace elements suitable as feed to 'direct reduction' smelters. Lowgrade ore. Low ...

Impact of quality of iron ore lumps on sustainability of ...
· For iron ore lumps, this change in source led to increases in the amounts of fines (owing to the greater fragility of BIFs compared to hematite ores) and the contents of Al 2 O 3 (owing to the contaminants found in clays), and SiO 2 present in iron ores (Santos and Brandao, 2003). These factors have exerted negative impacts on the steelmaking process.

Properties and EndUse Functionality of Iron Ore
Unlike iron ore sinter and pellets which are manufactured from iron ore fines and or concentrate, lump can be directly charged to the furnace without any preprocessing. As a result, lump has an inherently higher value compared with fines due to the avoidance of agglomeration costs. Australia is a significant producer of iron ore lump. While customers in traditional markets such as Japan ...
