Aluminium Smelting

6.1.3.2 Aluminium Smelting

Description

Quick Overview

Aluminium smelting in India is a crucial metallurgical industry, utilizing bauxite to produce various essential products.

Standard

Aluminium smelting is a significant part of India's manufacturing sector, utilizing bauxite as the primary raw material. It involves converting the bulky bauxite ore into aluminium, which is then used in various applications, including aircraft manufacturing and electrical wiring. The industry is strategically located in several states across India, primarily driven by the availability of cheap electricity and adjacent bauxite sources.

Detailed

Aluminium Smelting

Aluminium smelting is regarded as the second most important metallurgical industry in India. This industry is vital due to aluminium's light weight, corrosion resistance, conductivity, malleability, and strength when alloyed with other metals. This sector plays a crucial role in manufacturing a range of products, such as aircraft parts, utensils, and electrical wires. In India, aluminium has gained traction as a substitute for heavier metals such as steel and copper.

The raw material for this smelting process is bauxite, a dark reddish bulky rock. The manufacturing process for aluminium is electrified, requiring a stable supply of electricity and consistent access to low-cost bauxite ore to ensure profitability.

Aluminium smelting plants are distributed across several Indian states, including Odisha, West Bengal, Kerala, Uttar Pradesh, Chhattisgarh, Maharashtra, and Tamil Nadu. The strategic placement of these plants allows them to benefit from local resources and infrastructural support.
