Which one of the following metals can be obtained from Bauxite?a)Aluminiumb)Copperc)Irond)SilverCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Bauxite (Al2O3.nH2O) is an oxide ore of Aluminium...

Answer

Bauxite ore is the world’s main source of aluminum

Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world’s bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined into pure aluminum metal through the Hall–Héroult electrolytic process.

Answer

A. Aluminum, since Bauxite is the present of aluminum

Answer

Aluminum

Answer

Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions.. ..if answer helps.. so give it upvote... v@.**

Answer

A

Answer

Answer:

Introduction:
Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides. It is a reddish-brown rock that is primarily composed of aluminum-bearing minerals.

Explanation:
The metal that can be obtained from Bauxite is Aluminium.

Aluminium Extraction:
The process of extracting aluminium from bauxite involves two major steps: mining of bauxite and electrolytic reduction of alumina.

1. Mining of Bauxite:
- Bauxite is first mined from the earth using various techniques such as open-pit mining, strip mining, or underground mining.
- The bauxite ore is then transported to a processing plant where it is crushed and washed to remove impurities.
- The washed bauxite is then heated in a kiln at high temperatures to remove any remaining moisture and convert the aluminum hydroxide minerals present in the ore into alumina (aluminum oxide).

2. Electrolytic Reduction of Alumina:
- The alumina obtained from the bauxite is dissolved in a molten cryolite bath, along with other additives, to lower its melting point.
- The mixture is then electrolyzed in a cell called the Hall-Héroult cell, which consists of a carbon anode and a cathode made of graphite.
- A direct current is passed through the cell, causing the aluminum ions to be reduced at the cathode and deposited as molten aluminum metal.
- The molten aluminum is collected at the bottom of the cell and periodically tapped off.

Conclusion:
Thus, the metal that can be obtained from bauxite is aluminium. Bauxite is an important source of aluminum, which is widely used in various industries due to its light weight, high strength, and excellent corrosion resistance.
