Principle. Aluminium is produced by electrolytic reduction of aluminium oxide dissolved in molten cryolite. 2 increases and carbon consumption decreases. ... For this reason aluminium smelters are sited close to sources of inexpensive electricity, such as hydroelectric.
Why is aluminum smelting industry close to power sector?
You see, during electricity distribution the initial stages have high voltage whereas when it comes to the consumer end its value is greatly reduced(using step down transformers). Due to the high power requirements of aluminium smelters , aluminium smelting industry hence are always located close to the power sector.
Why is aluminium smelting an important industry?
Aluminium smelting – shortcut
Aluminium smelting is the second most important metallurgical industry in India. It is light, resistant to corrosion , a good conductor of heat, malleable and becomes strong when it is mixed with other metals. It is used to manufacture aircraft, utensils and wires.
How much electricity does an Aluminium smelter use?
The smelting of aluminium is the most energy-intensive stage of aluminium production, with each tonne of aluminium requiring around 15 MWh of electricity .
Which is the most important factor for the location of aluminium smelting plant *?
The prime factors in location of aluminium smelting industries are as follows : (i) Assured source of raw material, bauxite , at minimum cost as it is a bulky material at 4 to 6 tonnes of bauxite are required to manufacture 1 tonne of aluminium. 2) It’s labour and capital.
Is the raw material used in Aluminium smelting?
Alumina and bauxite are the two main raw materials in the aluminium making process. Aluminium is obtained by the electrolysis of alumina which extracts pure aluminium metal from alumina.
What are the advantage of aluminum Class 10?
Physical/Chemical Advantages of Aluminium
Strong . High strength-to-weight ratio . Resilient . Ductile at low temperatures .
What is Aluminium smelting 10th?
Hint: Aluminium smelting is that the process of extracting aluminium from its oxide, alumina , normally by the corridor-Héroult technique. Alumina is extracted from the ore bauxite by means of the Bayer technique at an alumina refinery.
What is the uses of aluminium?
Aluminium is widely used in the packaging industry for the production of coils, cans, foils, and other wrapping materials . It is also a component of many commonly used items such as utensils and watches. In construction industries, aluminium is employed in the manufacture of doors, windows, wires, and roofing.
Is Aluminium smelting industry is a key industry?
Aluminium smelting is the second most important metallurgical industry in India. ... Aluminium is an important metal as it is light, good conductor of heat and can be easily mixed with other metals.
Which country is the largest producer of aluminium?
| # 41 Countries Thousand Metric Tons | 1 #1 China 35,946.00 | 2 #2 Russia 3,554.37 | 3 #3 India 3,421.80 | 4 #4 Canada 3,255.98 |

How do you smelter aluminium?
- adding bath and alumina;
- anode;
- electrolysis;
- tapping; and.
- primary casting.
Why aluminium is more expensive than iron?
Aluminium is more reactive than carbon so it must be extracted from its compounds using electrolysis . Even though aluminium is more abundant than iron in the Earth’s crust , aluminium is more expensive than iron. This is mainly because of the large amounts of electrical energy used in the extraction process .
What are the requirements for locating Aluminium smelting industry?
The prime factors in location of aluminium smelting industries are as follows : (i) Assured source of raw material, bauxite, at minimum cost as it is a bulky material at 4 to 6 tonnes of bauxite are required to manufacture 1 tonne of aluminium.
What are the two main factors for location of Aluminium industry?
- Continuous supply of electricity.
- An assured minimum cost source of raw material.
Which industry is located near raw materials?
Similarly, the locations of pulp industry, copper smelting and pig iron industries are located near their raw materials. In iron and steel industries, iron ore and coal both are weight-losing raw materials. Therefore, an optimum location for iron and steel industries should be near raw material sources.
