Solution

The correct option is A
True

This process is also called Goldschmidt thermite process. It involves a highly exothermic reaction like:

$3 T i O_{2} (s)$ $+ 4 A l (s)$ $\to$ $2 A l_{2} O_{3}$ $(s)$ $+ 3 T i (l)$

$F e_{2} O_{3}$ $(s) + 2 A l (s)$ $\to$ $A l_{2} O_{3}$ $(s) + 2 F e (l)$

Do note that the reduced metal is in the fused (molten) form.

When $F e_{2} O_{3}$ is used, this process is also known as thermite welding (used to join railway tracks). But this is not the preferred method for extraction of Iron commercially.
