Metals in middle of the reactivity series are found in its sulphide or carbonate ores.
Calcination is a process of heating the ore with limited or no supply of air.The products are metal oxide with carbon dioxide.
Roasting is a process of heating the ore with supply of air.Products are metal oxide along with sulphur dioxide.
Example :Zn
ZnCO3-->ZnO+CO2
2ZnS+3O2-->2ZnO+2SO2
metals of high reactivity are obtained using electrolysis reduction
Example: NaCl-->(Na+)+(Cl-)

middle by calcilnation and roasting then by reduction reaction
2Zns + 3O2 = 2ZnO + 2So2
ZnO + C = Zn + Co
top by passing electricity
