Question

The extraction of iron from its ore The process of extraction of iron from iron oxide is as follows: 1.Impurities, such as sand and mud present in the iron ore (iron oxide, Fe O3), are removed by washing in a current of water. By doing this, the percentage of the metal oxide in the ore is increased or desired level. For ores containing magnetic impurities, a magnetic separation method is adopted. The raw materials are fed into the furnace, and hot air is injected at the bottom of the furnace. 2. When iron ore is heated in the presence of air to a high temperature just below its melting point, the ore is converted to oxides. The following changes take place during heating: Moisture is removed. Volatile impunties escape Coke reacts with oxygen from the hot air to produce heat and carbon monoxide, which is needed to reduce the iron oxide: 20(s) + 02 (g) 2CO(g) 3. The concentrated iron cre is reduced to metal at high temperature by using reducing agents such as carbon (coke Fe2O3 + 3CO 2Fe + 3CO2 4. After reduction, the metal still has some traces of impurities. Various refining processes are adopted to obtain pure metal. Part B Using the above summary for the extraction of iron, rank the common steps involved in the process of extraction of iron from its ore. Rank the steps from first to last. To rank items as equivalent, overlap them.
