Extraction of metal from the ore cassiterite involves

A

carbon reduction of an oxide ore

B

self-reduction of a sulphide ore

C

removal of copper impurity

D

removal of iron impurity.

Text Solution

Verified by Experts

The correct Answer is:
A
Cassiterite is `Sn_(2)O` - an ore of tin. Therefore, its extraction involves carbon reduction of the oxide ore. This ore has iron tungstate as impurity , so the extraction involves removal of iron ore. Options A and D is valid.
