Question

Read the source given below and answer the following questions :

The iron and steel industry is the basic industry since all the other industries — heavy, medium and

light, depend on it for their machinery. Steel is needed to manufacture a variety of engineering goods,

construction material, defence, medical, telephonic, scientific equipment and a variety of consumer

goods.

Production and consumption of steel is often regarded as the index of a country’s development. Iron

and steel is a heavy industry because all the raw materials as well as finished goods are heavy and

bulky, entailing heavy transportation costs. Iron ore, coking coal and limestone are required in the

ratio of approximately 4 : 2 : 1. Some quantities of manganese are also required to harden the steel.

Where should the steel plants be ideally located? Remember that the finished products also need an

efficient transport network for their distribution to the markets and consumers.

In 2016 with 95.6 million tonnes of crude steel production, India ranked 3rd among the world crude

steel producers. It is the largest producer of sponge iron. In 2016 per capita consumption of steel in the

country was only around 63 kg per annum against the world average of 208 kg.
