Question

Which of the following industries uses Bauxite as a raw material?
a. Aluminium
b. Steel
c. Jute
d. Cement

Answer 1

Hint:
- Bauxite is a result of the weathering process. The name bauxite is taken from its first area of analysis.
- The term bauxite is used for naturally occurring aluminium monohydrate mixtures.

Complete solution:

What?

- Bauxite is mainly a metallic mineral, but it is sometimes known as an agricultural mineral.
- It is the only ore used for large-scale processing of aluminium.
- Bauxite is primarily used as an aluminium ore and as a raw material for the production of aluminium chemicals.
- Aluminum-rich elements of igneous rocks weather to clay more quickly than mica and chlorite phyllites.
- The laterite type bauxite is formed in situ from crystalline rocks.
- Bauxite type terrarossa is overlaid with dolomite limestone.
- The bauxite used by the chemical and refractory industry in the United States in 1959 amounted to about 320,000 long dry tonnes.

Uses

- Bauxite is an aluminium-rich ore used in the manufacturing of aluminium (metallurgical bauxite) and refractory goods, chemicals or cement.
- Bauxite is a significant raw material of primary significance for the aluminium industry.
- It is also used in a range of non-metallurgical industries, such as refractory, abrasive, cement, steel and chemical.


Hence, the correct answer is option A.

Note:
- Bauxite is typically extracted by open-cast mining, with techniques that vary greatly depending on the location and are nearly often found near the surface.
- Bauxite is a clay mineral mixed with iron, mercury, titanium, sulphur, gallium, chromium, vanadium oxides as well as sulphuric calcium, iron and magnesium carbonate comprising a number of aluminium hydroxide modifications. In other words, approximately half of the periodic table is present in the typical bauxite.
