Mining iron ore or other iron-bearing materials from the ground is the first step to make iron and steel. Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite (Fe 2 O 3) or magnetite (Fe 3 O 4). Common types of iron ores and their iron contents are shown in Table 2.1

However, iron ore is a mixture of iron and oxygen, and other trace elements. To make steel, the iron needs to be separated from the oxygen and a tiny amount of carbon needs to be added. Both are accomplished by melting the iron ore at a very high temperature (1,700 degrees Celsius or over 3,000 degrees Fahrenheit) in the presence of oxygen (from the air) and a type of coal called
