Iron is one of the most common and useful metals in our lives. It is found in small jewelleries to huge buildings and structures. However, though there is a high demand of iron, pure iron is hard to find in nature. Scientific solution How is this metal extracted? Explain the scientific knowledge behind the extraction method. (Must be fully described in your own words to show you fully understand) Include pictures/ diagrams (Must be referred to in your paragraph) (maximum: 100 words) Iron normally exists in a form of iron oxide in iron ores. To extract pure iron, carbon is the main ingredient for this process. This is because carbon is more reactive than iron and it can displace (removing another substance from a less reactive metals) iron from iron oxide. This process is called reduction reaction. Iron(III) oxide + carbon → iron + carbon dioxide 2Fe2O3(s) + 3C(s) → 4Fe(l) + 3CO2(g)

In this process, a lot of heat is needed so it’s done in a blast furnace. You will also need limestone in this process to remove the impurity such as silicon dioxide.

Advantage: Extracting iron with carbon reduction is good as when carbon combines with oxygen, it will form carbon dioxide which will escape quickly and will not need to have further filtration to extract the metal. Also, not only carbon is used for reduction, it is also acting as a fuel source as iron needs a really high temperature to melt the iron ores. Disadvantages: Iron mining and extracting involves a lot of blasting, burning and drilling. Blasting and drilling will cause a lot of dust and is bad for health especially your lungs. The extraction process will create carbon dioxide. These pollution will cause a lot of problems for the citizens. For example, it is estimated to have 1.6 million deaths in China caused by air pollution. Evaluation Evaluate how successful the extraction method solve the problem with further evidence. (maximum: 50 words) I think that this extraction method is very effective, this is because its very simple and cheap, and can extract a lot of pure iron in a small amount of time. However, it causes a lot of air pollution. Works Cited You should print your
