(1x5) marks Iron is an important element, which our body needs for many of its functions. In our blood, it is the carrier of Oxygen. It is the fourth most common element in the earth's crust. In today's world, iron and its alloys are the most common industrial material due to its low cost and better mechanical properties. The extraction of iron metal takes place from its ore in a number of steps, which are summarized below. Iron ore, coke...
