Start Practising. In this explainer, we will learn how to describe the extraction of iron from its ore in the blast furnace. Extraction of iron is arguably one of the most important industrial processes on Earth. Iron is used to make steel, which is incredibly important for constructing transport vehicles and large buildings.

As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast ...

The actual reductant is CO, which reduces Fe 2 O 3 to give Fe(l) and CO 2 (g); the CO 2 is then reduced back to CO by reaction with excess carbon. As the ore, lime, and coke drop into the furnace (Figure 23.7 "A Blast …

Iron Ore is a type of rock that contains iron minerals, mainly hematite and magnetite. It is a vital raw material for the production of steel. The ores are rich in iron oxides, which range in colour from dark grey to bright yellow to deep purple to rusty red. The most common iron minerals are magnetite, hematite, goethite, limonite, and ...

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.
