The purpose of smelting an ore is to.......

In smelting,the substance added to combine with impurities to form a molten product is called what?

The reduction of an oxide by aluminium is called:

The reaction for obtaining the metal $(M)$ from its oxide $(M_{2}O_{3})$ ore is given by
$M_{2}O_{3(s)} + 2 Al(\ell) \xrightarrow{\text{Heat}} Al_{2}O_{3}(\ell) + 2 M_{(s)}$, $(s = \text{solid}, \ell = \text{liquid})$
In this case, $M$ is

Aluminum is obtained from alumina $(Al_2O_3)$ by the electrolysis of a molten mixture of:

Write down the reactions taking place in different zones in the blast furnace during the extraction of iron.
