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.

There are 3 primary methods for extracting ore : Underground mining Surface (open pit) mining Placer mining Some materials are deep under the earth's surface, requiring rock drilling and blasting before materials arrive at the surface. Other ores are closer to the earth's surface, and mining can operate without digging far underground.

What are the four types of iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone.These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
