After independence our great leaders thought of developing our industries. Without industries our country could not make progress. Therefore, plans were made to set up basic industries. Steel is the base of all heavy machinery and big steel plants were set up under the five-year plans. Now our country stands tenth in the industrialized countries of the world.
Industries can be divided under the two heads ( a ) Mineral-based industries ( b ) Agro-based industries. The industries like iron, steel, cement, aluminum and copper which draw the raw material from minerals are called mineral-based industries. The industries which draw their raw material from agriculture and forests are called agro-based industries.
Mineral Based Industries
Iron and Steel Industries :
Iron and steel industry is the base of all the industries. All types of machines which are used in other industries are made of steel. Therefore iron and steel industry is called key industry. Before independence we had steel mills at Jamshedpur, Bhadravati and Burnpur, but these mills could not meet our needs. Therefore, some more steel plants were set up under the five year plans at Bhilai (M.P.), Durgapur (West Bengal), Rourkela (Orissa), Bokaro (Bihar) and Salem (Tamil Nadu).
India has rich deposits of iron-ore and coal. Coal is required for extracting iron from its ore. Therefore most of the iron and steel plants have been set up near the iron and coal fields.
Railway Coach Factories :
Integral Coach Factory at Perambur near Chennai produces coaches for the railway trains. Another coach factory has been set up at Kapurthala in Punjab. These factories produce all types of coaches for the railways. Some coaches are being supplied to other countries.
Railway Engines :
A factory for the production of railway engines has been set up at Chittranjan in West Bengal. It used to produce locomotive engines. Now the locomotive engines are outdated and their place has been taken up by electric engines and diesel engines. The factory at Chittranjan now produces electric engines and another factory at Varanasi produces diesel engines.
A new industry making very fast progress is electronics. Radios, type-writers, television-sets, tape-recorders, computers and video games are only a few of the products being made.

Industries are the back-bone of a country. Industries give employment to millions of people. Different kinds of machines and articles of daily use are produced by industries. Industries depend for their raw material on agriculture or mines. If our industrial and agricultural production increases, we can get things easily and at cheaper rates. Industrial development can raise the living standard of out people.
