Description. 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).
Iron ore prices have fluctuated over the past decade. Prices declined from a high of US187 per tonne in February 2011 to a low of US41 in December 2015. During 2016, iron ore prices were stable until March, when they began to rise, and ended the year at US80 per tonne. Prices reached a high of 89 in February 2017 and then declined ...
· Ores carrying very high quantities of hematite (greater than ~ 60% iron) are known as "natural ore" or "direct shipping ore," meaning they can be fed directly into the BFBOF route. However, lowgrade ores need to be beneficiated before they can be used to make steel. To meet the size specifiion required for the highgrade DSO products and liberate the gangues from the lowgrade ...

Massive hematite ore (MHO) is a special highgrade iron ore used as lump ore in the process of obtaining direct reduced iron (DRI). The influence of porosity on the reducibility was investigated using optical and scanning electron microscopes. Hematite is the main component of the samples and occurs as granular crystals (10 m), microplates (1 m) and euhedral martite (10 to 30 m).
· Iron ore classifiion: Critical insights for resource. A powerful iron ore classifiion system is a critical prerequisite. Without a sufficiently and appropriately characterised resource, modelling will be inaccurate reducing an organisations ability to implement cost reductions and productivity gains across the iron ore value chain.
Classifying Iron Ore. ABSTRACT In the present article a new tool to determine environmental sustainability the energy impact index EII was developed to classify different iron mine projects according to two main parameters including energy consumption and CO 2 emissions The EII considers the characteristics of the mineral such as the quality size hardness iron ore grade reducibility ...

Highgrade hematite ore is referred to as direct shipping ore (DSO) because after it is mined, the ores go through a relatively simple crushing and screening process before being exported for use in steelmaking. Australia's hematite DSO from the Hamersley region in Western Australia averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but ...
