write a short note on aluminum industry
Answers
Explanation:
Aluminium Industry is the second most important metallurgical industry in India. Aluminium has gained popularity as a substitute of steel, copper, zinc and leads in a number of industries because it is light metal, resistant to corrosion, a good conductor of heat, malleable and becomes strong when it is mixed with other metals. There are 8 aluminium smelting plants in the country located in Odisha (formerly Orissa) (Nalco and Balco), West Bengal, Kerala, Uttar Pradesh, Chhattisgarh, Maharashtra and Tamil Nadu. In 2004, India produced over 600 million tons of aluminium. Bauxite, the raw material used in the smelters is a very bulky, dark reddish coloured rock. The flow chart given below shows the process of manufacturing aluminium. Regular supply of electricity and an assured source of raw material at minimum cost are the two prime factors for location of the industry.
Process of Manufacturing in Aluminium Industry
• Bauxite: It is use as raw material
• Alumina: Bauxite crushed and alumina dissolved out > Bulk ore shipped to site of smelter> Calcinated petroleum coke from a refinery > Aluminium refinery: Pitch from a colliery
• Cryolite: A molten metal acts as an electrolyte > Aluminium Smelter> Passage of electricity.
