Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires

This has eventuated because of the nature of the ore mined locally and used in the process. Early pioneering experiments failed to successfully smelt iron from New Zealand's west coast ironsand deposits because the magnetite ore (Fe 3 O 4), as it is known, is locked in with minerals such as titania and silica. These bonded oxide impurities are

Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand. This magnetic sand is an iron ore called magnetite, which when combined with carbon

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

The inclination and the rotary motion of the kiln ensure that the raw materials move from the feed end to the discharge end of the kiln and during this movement the actual reduction of iron ore to iron takes place. The material discharged from the kiln is taken to a rotary cooler for cooling and the cooled product is separated from the coal char.
