The iron ore is reduced in a blast furnace by reaction at high temperature with carbon. The raw materials are specially prepared for the blast furnace. Iron ore is mined and prepared into "sinter" or pellets for the steel making process. For example, taconite, a common low grade iron ore, is roughly 28 wt% iron in the form of Fe 2 O 3, Fe 3 ...

It's a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. This concentrated ore is 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.

Iron making. The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

it is much easier to extract metals from their oxides because you can easily perform a redox reaction with the metal's oxide by adding carbon and then heating it. the carbon will react with the oxygen in oxide and form co2 and hence make the metal purer than before. 1 comment.

How Iron Was Made. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s waterpowered hammers ...
