Question

Which of the following groups of factors is a prime group for the location of aluminium smelting plants?
a. Capital and Market
b. Raw materials and Electricity
c. Labour and Raw material
d. Capital and Transport

Answer 1

Hint:
Aluminum Industry is the second most significant metallurgical industry in India. Aluminum has picked up fame as a substitute of steel, copper, zinc, and leads in various enterprises since it is light metal, impervious to consumption, a decent channel of warmth, moldable and becomes solid when it is blended in with different metals.

Complete solution:
Refining is only extraction of aluminum from its metal. Aluminum refining plant's area relies upon accessibility of crude material and is great gracefully of power.
The prime elements in area of aluminum refining ventures are as per the following :
(I) Assured wellspring of crude material, bauxite, at least expense as it is a massive material at 4 to 6 tons of bauxite are needed to make 1 ton of aluminum.

(ii) 18600 kWh of power is required per ton of metal for purifying aluminum. Thus, standard flexibility of intensity is another significant factor for the area of the business.
Orissa produces around 45 percent of India's bauxite. Subsequently, aluminum refining plants are situated in Orissa. Additionally, the Hirakud dam gives modest hydroelectricity to the advancement of the aluminum business in the state.

West Bengal, Kerala, Uttar Pradesh, Chhattisgarh, Maharashtra, and Tamil Nadu, are different states where aluminum purifying plants are found. INDAL, HINDALCO, MALCO, NALCO and Aluminum Corporation of India are names of the major purifying plants.

Hence, the correct answer is option B.

Note:
Aluminum begins from bauxite, a mineral ordinarily found in the dirt of different tropical and subtropical districts. When mined, aluminum inside the bauxite mineral is synthetically extricated into alumina, an aluminum oxide compound, through the Bayer cycle. In a subsequent advance, the alumina is purified into unadulterated aluminum metal through the Hall–Héroult process.
