Question

Aluminium is extracted by processing which ore?
A. Alumina
B. Bauxite
C. Haematite
D. Muscovite

Answer 1

Hint: Aluminium is abundantly available and covers 8% of the Earth’s crust. It is also the third most plentiful component after oxygen and silicon.

Complete answer: Aluminium is a delicate, gleaming white, corrosion-resistant metal. It is the most bountiful metal in the world. Bauxite mineral (Al2O3.xH2O) is the main source of aluminium and is a combination of hydrated aluminium oxide. Aluminium can likewise be extracted from cryolite (Na3AlF6) and alunite. The bauxite metal contains impurities like ferric oxide and silica as well. The extraction process is first put through gravity separation of ferric oxide impurities by the process of magnetic separation and then through various chemical processes. These processes include Baron’s process.
Looking at the options given:
Option A- Alumina is not the correct answer. It is the raw form of aluminium.
Option B- Bauxite is the correct answer. Aluminium is extracted from bauxite ore.
Option C- Haematite is an iron oxide that is abundantly available in the Earth’s crust. . This is not the correct answer.
Option D- Muscovite is the most prevalent mineral that is found in the mica family. This is an incorrect answer.
Therefore “B” is the correct answer.

Note: It is additionally found in gemstones, for example, garnet, topaz and chrysoberyl. Aluminium is a substantial component and is the most ordinarily utilized non-ferrous metal.
