Which method do you suggest for extraction of high reactivity metals…

WebMetals such as iron, zinc, lead, copper, etc., are in the middle of the reactivity series. These are moderately reactive metals and are usually present as sulphides or carbonates. A metal is obtained from its ore by the processes of reduction or by electrolysis. In the reduction process, it is the oxide ore that is reduced. WebZinc oxide so obtained is reduced to zinc metal by heating with carbon (a reducing agent). ZnO + C ⇨ Zn + CO. Extraction of Iron: Hematite ore (Fe 2 O 3) is heated with carbon to be reduced to iron metal. Fe2O3 + 3C ⇨ 4Fe + 3CO2. Extraction of lead from lead oxide: Lead oxide is heated with carbon to be reduced to lead metal.
