Iron Ore on a conveyor [image 13511] Digging ore from the earth is only half the battle. Often just as challenging and costly is the processing of the ore, which takes place in mills, smelters and refineries. Processing requires crushing and grinding to liberate the minerals. After liberation, separation processes are used to concentrate the ...
Analysis of the current technical solutions for the processing of iron ores showed that the highgrade ores are directly exposed to metallurgical processing; by comparison, lowgrade ores, depending on the mineralogical and material composition, are directed to beneficiation including gravitational, magnetic, and flotation processes or their combination. Obtaining highquality concentrates ...
Mineralogical characterization helps in identifying the mineral distribution in the ore sample and provides the textural information, in turn assisting in determining the grade of iron ore by describing the modal distribution of both the ore as well as the gangue minerals. It also provides information essential for the downstream processings.

Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through threestage crushing and thus segregated by screening into 1040 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce 100% fine product. Yield from the plants has been ...

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
