Question

Name the main variation of iron ore and the iron content present in each one of them ?

Answer 1

Hint:
Magnetite, Hematorite, Goethite and Limonite or Sidright are different types of iron ore. Iron is usually found in the form of magnetite, which is 72.4% iron, hematite with 69.9% iron, 62.9% iron with iron, 48.2% iron is a Limionite or Sidright.

Complete answer:
Iron ore are rocks and minerals from which metal iron can be financially removed. Ores are usually rich in iron oxides and dark brown colors, bright yellow, or deep corrosion variation in purple to red.

Very high amounts of hematite or magnetite are known as "natural ore" or "direct shipping ore", which means that they can be fed directly in the blast furnace making iron making. Iron ore is cast iron, which is used to make pig iron, which is one of the main raw materials to make steel - 98% of mining iron ore is used to make steel. In 2011, the Financial Times estimated that iron ore "is more integral than the global economy, perhaps leaving oil".

Iron is the most commonly used metal in the world - the iron ore is the main component, approximately 95% of all metal used per year. It is mainly used in structures, ships, automobiles and machinery.

Iron-rich rocks are common all over the world, but the commercial mining functions of ore-class are dominated by the countries listed in the table. For the deposits of iron ore, the major obstacle deposit of economics is not necessary, because it is not particularly difficult that there is enough ton weight of the rocks. The main obstacle is the status of iron ore relative to the market, the cost of rail infrastructure to bring it to the market and the necessary energy costs to do so.

Note:
Mining iron ore is a high volume, low margin business, because the value of iron compared to base metals is quite low. It is highly capital-staple, and requires significant investment in rail such as infrastructure to carry ore for the cargo from the mine. For these reasons, the production of iron ore is centered in the hands of some major players.
