Concentration is the second step in taconite ore processing. As the iron ore minerals are liberated by the crushing steps, the ironbearing particles must be concentrated. Because only about 33 percent of the crude taconite becomes a shippable product for iron making, a large amount of gangue is generated.
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.

Whilst drilling results of base metals are reported in a percentage per tonne (%), drilling results of precious metals are reported in grams per tonne (g/t). For an investor it is very important to know if a drill result is low, medium or high grade: this gives you the first impression of the possible financial outcomes of the deposit.

While Britain had good iron ore reserves, the iron produced was of low quality with plenty of impurities, limiting its use. There was plenty of demand but not much was produced as wrought iron, which had many of the impurities hammered out, took a long time to make, and was available in cheaper imports from Scandinavia.
The following Iron Ore specifications guide contains the primary specifications and methodologies for Platts Iron Ore assessments throughout the world. These are the timestamps used for Platts iron ore assessments. Data reported at or after these timestamps is not considered in the assessment process. Asia: Singapore Atlantic: London
Demand for iron ore will be supported by the continued urbanization and industrialization of the developing world such as China, India, the CIS and the Middle East.
Mineral processing. In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores .

Energy and Environmental Profile of the Mining Industry A metal is an opaque lustrous elemental substance that is a good conductor of heat and electricity. It is also malleable and ductile, possesses high melting and boiling points, and tends to form positive ion chemical compounds.
With an ore body 4km long, 80m thick and reaching a depth of 2km, LKAB's Kiruna is the world's largest, most modern underground iron ore mine. Since mining began at the site over 100 years ago, LuossavaaraKiirunavaara AB (LKAB) has produced over 950Mt of ore, yet only one third of the original ore body has been extracted.
Iron ore can be upgraded to a higher iron ore content through beneficiation. 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.
