(B) In the process of metallurgy,a flux is added to remove gangue (impurities). Flux reacts with gangue to form a fusible material called slag. For example,if the impurity is $SiO_2$ (acidic),a basic flux like $CaO$ is added. $CaO + SiO_2 \rightarrow CaSiO_3$ (Calcium silicate). Thus,the slag consists of molten impurities generally in the form of metal silicate.
