Aluminium Ore, Bauxite Mining, Uses, Properties, Distribution Map

In 2023, India is the fifth-largest producer of bauxite in the world, with a 0.67% increase in output compared to 2022. From 2018 to 2022, production grew at an average rate of 0.15%, and it is expected to rise by 3% each year from 2023 to 2027. India produces 6% of the world’s bauxite, with the biggest producers being Guinea, Australia, China, and Brazil. In 2023, bauxite exports from India also increased by 0.67%, mainly going to Nepal. India’s bauxite exports are predicted to grow at an average rate of 3.33% from 2023 to 2027.

Aluminium Ore

Bauxite is the main ore for aluminum, with nearly all aluminum produced from it. Bauxite is not a mineral it’s a rock made mostly of aluminum-bearing minerals and forms when laterite soils lose silica in wet climates. Its composition varies, including hydrous aluminum oxides and clay minerals. Bauxite is soft and usually white to gray, sometimes stained by iron. It has an earthy luster and low specific gravity (2.0 to 2.5).

To produce aluminum, bauxite is crushed and purified through the Bayer Process, which uses sodium hydroxide to extract aluminum. The aluminum hydroxide is then heated to form alumina, which is smelted using the Hall-Heroult Process, requiring a lot of electricity. Most aluminum in the U.S. is produced in Canada, where electricity costs are low.

Aluminium Ore Bauxite Mining

Aluminium Ore Bauxite (raw material) is bulky, and it is preferable to remove moisture and impurities before transporting its ore over long distances in order to achieve economic production. It takes 6 tonnes of bauxite to produce 1 tonne of aluminum. The aluminum industry is energy-intensive, with power costs making up 30-35% of total expenses, so affordable electricity is essential.

There is a shortage of primary aluminum to meet rising demand, which has increased by over 1 million tonnes a year, while production stays steady at about 0.5 million tonnes. Since this industry needs lots of power, finding suitable locations in India is challenging.

Aluminium Distribution in India

1. Odisha

Odisha is India’s largest bauxite-producing state, accounting for more than half of total production. The state’s total recoverable reserves are estimated to be 1,370.5 million tonnes. The main bauxite belt is in the districts of Kalahandi and Koraput, and it extends into Andhra Pradesh.

2. Jharkhand

Jharkhand has been estimated to have 63.5 million tonnes of recoverable bauxite reserves of all grades. These reserves are spread across Ranchi, Lohardaga, Palamu, and Gumla districts. Bauxite can also be found in the districts of Dumka and Munger. Lohardaga and surrounding areas have high-grade ore.

3. Maharashtra

Maharashtra accounts for approximately 10% of total bauxite production in India. The state’s total recoverable reserves are estimated to be in the order of 87.7 million tonnes. The largest deposits are found in the Kolhapur district, where the plateau basalts are capped. In the Kolhapur district, rich deposits with alumina content ranging from 52 to 89 percent can be found in Udgeri, Dhangarwadi, Radhanagari, and Inderganj.

4. Chhattisgarh

Chhattisgarh produces more than 6% of India’s bauxite. The Maikala range in Bilaspur, Durg districts, and the Amarkantak plateau regions of Surguja, Raigarh, and Bilaspur have rich bauxite deposits.

5. Madhya Pradesh

The main producers in Madhya Pradesh are the Amarkantak plateau area, the Maikala range in the Shahdol, Mandla, and Balaghat districts, and the Kotni area of Jabalpur district. Andhra Pradesh (Vishakhapatnam, East Godavari, and West Godavari), Kerala (Kannur, Kollam, and Thiruvananthapuram), Rajasthan (Kota), Uttar Pradesh (Banda, Lalitpur, and Varanasi), Jammu and Kashmir (Jammu, Poonch, and Udhampur), and Goa also have some bauxite.

Aluminium Advantages

  • Aluminium is a versatile metal that has several advantages, including being lightweight and flexible.
  • It can be cast, melted, formed, machined, and extruded into a variety of shapes and then fabricated to suit a wide range of applications.
  • Because of their lightweight, corrosion resistance, and ease of fabrication, aluminium sheets are the preferred material for projects such as vehicle panelling, artwork, building cladding, and kitchen fitting, among others.
  • Despite popular belief, aluminium is completely recyclable and retains all of its original properties during the recycling process.
  • Using recycled metal during production is more cost-effective than using prime metal mined from the ground, so as much recycled material as possible is used.

Aluminium Uses

  • It is used in manufacturing aircraft, automobiles, rail wagons, ships, and machinery.
  • It is used in the manufacturing of domestic appliances and utensils.
  • It is also used to fabricate doors, windows, and screens.
  • Aluminium can be rolled into thin sheets called aluminium foils. These are used for wrapping and packaging food.

Aluminium Ore and Bauxite Mining FAQs

Is aluminium a metal?

Aluminium is a silvery-white metal that is lightweight. It is pliable and malleable.

Is aluminium metal or an alloy?

Aluminium is the 13th element in the periodic table and is a silvery-white metal. One surprising fact about aluminium is that it is the most common metal on the planet, accounting for more than 8% of the Earth's core mass. It is also the third most abundant chemical element on Earth, after oxygen and silicon.

Is aluminium or aluminum correct?

Aluminum was officially adopted by the American Chemical Society (ACS) in 1925, but the International Union of Pure and Applied Chemistry (IUPAC) accepted aluminium as the international standard in 1990. As a result, we have aluminum used by English speakers in North America and aluminium used everywhere else.

What are the 3 uses of aluminium?

The metal and its alloys are widely used in the manufacturing of aircraft, building materials, consumer durables (refrigerators, air conditioners, cooking utensils), electrical conductors, and chemical and food-processing equipment.

Can aluminium rust?

Although aluminium does not rust, it does corrode. The aluminium oxide coating is highly resistant and self-repairs if damaged, keeping the metal relatively corrosion-free. However, certain factors can cause the coat to become unstable, exposing the metal.

Is aluminium magnetic?

Aluminium is not magnetic under normal conditions, owing to its crystal structure. Along with other metals such as magnesium and lithium, it is classified as a paramagnetic material.

Where is bauxite found in Orissa?

Bauxite is found in the Eastern Ghats of southern Odisha, in the districts of Koraput, Rayagada, Kalahandi, and Bolangir.
