METALLURGY:-
The extraction of metals from their ores and then refining them for use
When cinnabar heated it will convert into first mercuric oxide and then mercuric acid to mercury

Answer:
The process of extraction of metals from their ores and purify them in order to use them is called metallurgy.
Explanation:
Mercury(Hg) belongs to metals low in the reactivity series.
Mercury is present in the form of its sulphide ore HgS called Cinnabar and are extracted by the roasting. After that, we get mercuric oxide which is further reduced to Mercury by heating.
Reaction:
2HgS + 3O2 ⇨ 2HgO + 2SO2
2HgO ⇨ 2Hg + O2
