Vedclass · Answer

(B) In the extraction of iron,haematite $(Fe_2O_3)$ is reduced to pig iron in a blast furnace using coke and limestone. This is a correct match.Copper matte is a mixture of $Cu_2S$ and $FeS$,and its conversion to $Cu$ involves Bessemerization (self-reduction),but the option is often considered incomplete or less accurate compared to the blast furnace process for iron.Galena $(PbS)$ is converted to $PbO$ by roasting (not calcination).Red bauxite is purified by the Bayer process,and $Al$ is obtained by Hall-Heroult electrolytic reduction,but the process sequence is distinct.
