The quality of the tools made from it was highly variable, depending on the region from which the iron ore was taken and the method used to extract the iron. The chemical nature of the changes taking place during the extraction were not understood; in particular, the importance of carbon to the metal''s hardness.
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.
More recently, densemedia separation has been incorporated into platinumgroup metals flowsheets, to separate barren waste rock from ore prior to milling. The beneficiation of chromite and iron ore using gravity and magnetic separation and vermiculite upgrading by dry separation techniques, have become important activities.

Chemical separation of impurity elements, such as silicon, aluminum, and sulfur, from iron ores often occurs in the processing to remove phosphorus from the ore. The treatments may include caustic or acid leaching of the ore, with or without a heating treatment, and .
Iron Ore Magnetic Separation. The largest development in the ironore industry, using magnetic concentration, is at the plants of Witherbee, Sherman Co. at Mineville, N. Y., where about 1,200,000 tons of crude ore were mined and separated in 1916.
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

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.
Mar 07, 2010· The conversion of the Iron ore to the metallic Iron is a chemical reduction, but depends upon the chemical nature of the ore being used, for example: 2 Fe2O3 + 3 C (as coke) > 4 Fe + 3 CO2 (g) This is actually a series of reactions that are temperature dependent. 3 Fe2O3 + CO > CO2 + 2 Fe3O4 (Begins at 850° F) Fe3O4 + CO > CO2 + 3 FeO ...
