Answer:
The metals in the middle of the activity series (Zn, Fe, Pb, etc.) are moderately reactive. ... Therefore before extracting metals form their respective ores, the metal sulphides and carbonates must be converted into metal oxides. For instance, sulphide and carbonate ores of zinc are heated to convert into their oxides.
