Mini steel plants are smaller, have electric and induction furnaces, and use steel scrap and sponge iron as raw material. They may have re-rollers manufacturing bar and rods. They produce mild and alloy steel and also liquid steel which are turned into ingots. They are decentralized secondary units scattered across the country to meet local demands. An integrated steel plant is large and handles everything in one complex from assembling raw material and melting of iron ore in the blast furnace to steel making, rolling and shaping. They are usually concentrated near the sources of raw materials and market. Presently there are 10 integrated steel plant in India, which are as follows : (a) Indian Iron and Steel Company, IISCO at Kulti and Burnpur, West Bengal. (b) Tata Iron and Steel Company, TISCO at Jamshedpur, Jharkhand. (c) Visveswarayya Iron and Steel Plant, at Bhadravati, Karnataka. (d) Bhilai Steel Plant, at Bhilai, Chhattisgarh. (e) Bokaro Steel Plant, at Bokaro, Jharkhand. (f) Durgapur Steel Plant, at Durgapur, West Bengal. (g) Rourkela Steel Plant, at Rourkela, Orissa. (h) Vishakhapatnam Steel Plant, at Vishakhapatnam, Andhra Pradesh. (i) Salem Steel Plant, Salem, Tamil Nadu. (j) Vijayanagar Steel Plant in Karnataka. Though India is an important iron and steel producing country in the world, we are not able to perform to our full potential largely due to the following problems faced by the industry: (i) High costs and limited availability of coking coal. (ii) Lower productivity of labour. (iii) Irregular supply of energy. (iv) Poor infrastructure Today with 32.8 million tonnes of steel production, India ranks ninth among the world crude steel producers. It is the largest producer of sponge iron. In spite of large quantity of production of steel, per capita consumption of steel per annum is only 32 kg.
