Aluminium, a lightweight silvery white metal is the most abundant metal on the planet, as well as one of the most affordable. The Indian Aluminium Industry is a highly concentrated industry, with India being the world's second-largest producer. It has a share of nearly 5.3 percent of global aluminium output, with the top five companies accounting for the majority of the country's output. In spite of rising demand, India's aluminium industry is thriving at an incredible rate. India's primary aluminium exports have risen rapidly in recent years, with exports accounting for 54 percent of total production in FY20, up from 46 percent in FY16. This article will explain to you about Aluminium Industries which will be helpful in preparing Geography for the UPSC Civil service exam.

Aluminium Industries in India

• Aluminium is an important strategic metal for India's economy.
• After the iron and steel industry, aluminium is the second most important industry.
• Aluminium is used in the production and distribution of electricity in the modern world (it is a good conductor of electricity), household utensils and electric appliances, aircraft manufacturing, rail coaches, nuclear and defence accessories, and so on.
• It's also the fastest-growing metal, with nearly a 20-fold increase in the last 60 years (compared to 6 to 7 times for other metals).
• In the downstream sector, it created over 8 lakh jobs directly and indirectly, as well as over 4000 SMEs.
• In terms of the Bauxite reserve base, India ranks seventh in the world.
• Bauxite is the primary raw material used in the production of aluminium.
• The National Mineral Exploration Trust was set up to ensure an increase in aluminium production and to make the required volume of raw materials available to the industries.

Segments Of Aluminium Industries

• There are two basic segments in the aluminium industries such as:
  • Upstream
  • Downstream
• Bauxite mining is used in the upstream sector to produce primary aluminium from raw materials.
• The downstream sector involves the transformation of aluminium into semi-finished products such as rods, bars, castings, forgings, and so on.

Production Process

• Aluminium smelting is the extraction of aluminium from its oxide, alumina, using the Hall-Héroult process.
• An alumina refinery uses the Bayer process to extract alumina from the ore bauxite.
• Since this is an electrolytic process, an aluminium smelter consumes a lot of electricity.
• To reduce their overall carbon footprint, smelters are often located near large power plants, often hydroelectric ones.

Production Process

Evolution

• The aluminium industry is the newest of all the industries. Only in 1886 was aluminium discovered.
• Although bauxite, the primary ore of aluminium, is found throughout the earth's crust, large concentrations of it are uncommon.
• When the Aluminium Corporation of India was founded in 1937, it was the first attempt to manufacture aluminium in India.
• However, the company's first attempt to produce aluminium was postponed. In India, the history of the aluminium industry can be traced back to the following years:
• 1938:The Indian Aluminium Company began production in Allupuram, Kerala, in 1938.
• The government announced several facilities in 1940 to give the industry a moral and financial boost, including an import tax exemption and a heavy duty on imported aluminium.
• 1942: The Aluminium Corporation of India was able to begin production in West Bengal's Jaykay Nagar.
• Second Five Year Plan: During the Second Five-Year Plan, the following aluminium plants were established:
  • In 1943, the Indian Aluminium Company (INDAL) began fabricating sheets from imported alumina, and in 1948, it began producing alumina from indigenous bauxite.
  • 1958: Hindustan Aluminium Company (HINDALCO) – Renukoot, Uttar Pradesh
  • It is India's largest integrated primary producer of aluminium and semi fabricated products, having been founded.
• Third Five Year Plan: During the Third Five-Year Plan, the following aluminium plants were established:
• 1965: Mettur is home to the Madras Aluminium Company (MALCO), which has been in operation since (Tamil Nadu).
• 1965: The Bharat Aluminium Company Limited (BALCO) was founded.
• Bauxite is obtained from the Phutkapahar region of Amarkantak by its unit at the Korba Aluminium Complex in Chhattisgarh.
• 1970: The Indian Aluminium Company (INDAL) was founded in Belgaum, Karnataka.

Location Factors And Distribution

• The factors which influence the location of aluminium industries are as follows
  • Regular and cheap supply of electricity.
  • Assured supply of raw material - Bauxite
  • Availability of water
• Because of the above factors, the majority of aluminium industries are concentrated in the following areas: Odisha, West Bengal, Kerala, Uttar Pradesh, Chattisgarh, Maharashtra and Tamil Nadu.

Challenges Faced by Industries

• High power costs and a lack of power are major roadblocks in the development of the aluminium industry.
• Disconnection of power supplies from the grid system affects production.
• There is a complete loss of power. Smelters are increasingly developing their own thermal power plants.
• Old technology in production – Smelter units that are decades old consume more energy and have higher production costs.
• Vast bauxite deposits, recently discovered on India's east coast, remain untapped.
• Controlled prices for selling aluminium to state electricity boards are unprofitable for the industry and result in a loss.
• The price controls are also applied to commercial grade metal. Profitability suffers as a result.
• Indian industries find it difficult to compete in the international market due to high input costs.
• Cryolite and fluoride, for example, are still imported as raw materials.
• Producing aluminium at a low cost on a small scale is difficult because production costs decrease as scale increases (mainly power cost).
• The establishment of an aluminium industry necessitates a significant capital investment.
• Small business owners will find it difficult to break into the aluminium industry.
• Setting up an aluminium industry takes a long time.
• For example: It takes about 3-4 years for a plant the size of BALCO to become operational.
• Control over bauxite mines: Existing players already have control over the country's known bauxite mines, resulting in price manipulation and a negative impact on the industry.
• Power shortage: The growth of the aluminium industry has been hindered by a power shortage, which is one of the most important components of aluminium production.
• Government policies and bureaucratic processes, such as environmental clearance and bauxite mine allotment, have also contributed to the industry's lag.
• Land: Existing players can easily expand because brown-field projects are easier to set up than new green-field projects.
• As a result, the opportunities for new players in the industry are dwindling.
• International competition: India has the best grade bauxite, but its aluminium production lags behind Australia, Canada, France, and the United States.
• One of the main reasons for India's industry's growth impediments is the lack of affordable power.
• Strikes and labour unrest are also impeding the growth of India's aluminium industry.

Advantages- Aluminium

• Aluminium is a highly versatile metal that offers a number of benefits, including being lightweight and flexible.
• It can be cast, melted, formed, machined, and extruded, allowing it to be formed into a variety of shapes and then fabricated to suit a wide range of applications.
• Aluminium sheets are the go-to material for projects like vehicle panelling, artwork, building cladding, and kitchen fitting, among others, due to their lightweight, corrosion resistance, and ease of fabrication.
• Contrary to popular belief, aluminium is 100 percent recyclable and retains all of its original properties during the recycling process.
• It is more cost-effective to use recycled metal during production than prime metal mined from the ground, so as much recycled material as possible is used.

Conclusion

With the government's increased focus on infrastructure, it is expected that aluminium demand from the electrical, building and construction sectors will increase significantly in the domestic market. In the coming years, government initiatives such as the "Make in India" scheme, the "100 Smart Cities" programme, 100 percent rural electrification, indigenous space programmes, indigenization of defence procurement and production, and others are expected to boost aluminium demand significantly.
