Question

Bauxite (Aluminum ore) is mixed with cryolite during the extraction of aluminium due to which of the following reason(s)?
(a) it reduces the melting point of the ore
(b) decreases the electrical conductivity
(c) increases its melting point of the ore
(d) acts as a good solvent​

Answer 1

Answer:

a) and d) are correct answer

Answer 2

Cryolite is added to Bauxite option (a) to reduce the ore's melting point.

Importance of Cryolite addition:

• Bauxite is the Aluminium ore which is used for the Aluminium extraction.
• Usually, Cryolite is added to the ore which reduces the melting point of the ore.
• It also do one more action that is it increases the electrical conductivity of the ore.
• Thus, we can say that Cryolite is useful in melting point reduction and enhancing conductivity. So that there will be maximum extraction of Al from its ore.
• So option (a) is the correct answer.
