Extraction of metal from the ore cassiterite involves

A

Carbon reduction of an oxide ore

B

Self-reduction of sulphide ore

C

Removal of copper impurity

D

Removal of iron impurity

Text Solution

Verified by Experts

The correct Answer is:
A, D
Cassiterite `(SnO_(2))` :
`{:(SnO_(2)+ C rarr SnO + CO),(SnO_(2) + C rarr Sn+ CO_(2)):}}"Carbon reduction"`
Also iron is present as impurity in this ore.
