Barsua iron ore mine in India has adopted Remco Jigs for beneficiation of lowgrade iron ore fines. Bateman''s Apic jig is being used in iron ore mines of South Africa and has demonstrated how the technology is suitable for the separation of fine ferrous ores. A Batac jig is installed to reduce alumina content of iron ore fines from Noamundi
The concentration of Ore can define as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore for the extraction of metal. In this content definition and methods for the concentration of ore are explained along with the definition of ore and its types.
The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:
It is essential that the Al2O3 (alumina) be obtained substantially free from these impurities as otherwise the iron oxide and silica would be reduced and contaminate the metallic aluminum produced in the Hall (or Heroult) Process. The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process.

The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it.

Available world iron ore resources. Iron is the most abundant element on earth but not in the crust. [citation needed] The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.
Iron Ore: Mineralogy, Processing and Environmental Issues . summarizes recent, key research on the characterization of iron ores, including important topics such as beneficiation (separation and refining), agglomeration (, production of pellets or powders), blast furnace technology for smelting, and environmental issues relating to its production.
Metallurgy consists of three general steps: (1) mining the ore, (2) separating and concentrating the metal or the metalcontaining compound, and (3) reducing the ore to the metal. Additional processes are sometimes required to improve the mechanical properties of the metal or increase its purity.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores.
