Question
Describe the Aluminium refining industry.
✓
Answer
$>$ Aluminium has characteristics like light weight, strength, malleability, good conductor of electricity and resistance to corrosion.
$>$ Its importance has increased as the alloys obtained after mixing it with tin, copper, zinc and magnesium are used in manufacturing of vehicles, railway, aircraft and machinery.
$>$ For the production of one tonne of aluminium, approximately $6$ tonnes of bauxite and $18,600\ KW$ of electricity is needed.
$>$ Electricity alone constitutes $30$ to $40\%$ of the production cost.
$>$ This indicates that location of this industry is influenced by the availability of bauxite and inexpensive electricity.
There are 8 aluminium plants in the country today.
$>$They are located in Orissa, West Bengal, Kerala, Uttar Pradesh, Chhattisgadh, Maharashtra and Tamil Nadu.
$>$They annually produce about $6.2$ lakh tonnes of aluminum.
