Metals of low reactivity series are extracted by the process of roasting and calcination.
Roasting is the extraction of metals by heating in presence of oxygen.
I.e; Cinnabar[HgS] is heated with O2 which gives SO2 and Hg.
HgS + O2 ------------ Hg + SO2
While calcination is heating the ore without 02.
I.e; Ferric oxide[Fe3O4] is heated with carbon then they release Fe and CO2.
