metals of high reactivity series are Na, K, Ca, Mg
eg exaction of na
2nacl--------2na+cl2
metal of low reactivity series are cu, hg, ag, au
eg 2hgo-------- 2hg+o2
hg2s+o2-------''hgo+so2
metal of moderate reactivity series are al, fe
eg znco3---------zno+co2 ( calcinattion)
2zn+3o2---------2zno+2so2(roasting)
if helpful or right mark as brainlist....

✨✔️HERE IS YOUR ANSWER....
✔️ EXTRACTING METALS LOW IN THE REACTIVITY SERIES :-
✨Metals low in the reactivity series are very unreactive. The oxides of these metals can be reduced to metals by my alone.
For example :- Cinnabar is an Ore of mercury. When it is heated in air it first converted into mercuric oxide. Mercuric oxide is then reduced to mercury on further heating.

✔ EXTRACTING ️ METALS IN THE TOP OF THE REACTIVITY SERIES :-
✨The metals high up in the reactivity series are very reactive. They cannot be obtained by heating. These metals have more affinity for oxygen than carbon. The metals are obtained by electrolytic reduction.
✨REFINING OF METALS....
IN THIS PROCESS IMPURE METAL IS MADE THE ANODE AND A THIN STRIP OF PURE METAL IS MADE OF CATHODE. ON PASSING THE CURRENT THROUGH THE ELECTROLYTE, THE PURE METAL FROM THE ANODE DISSOLVES INTO THE ELECTROLYTE. AN EQUIVALENT AMOUNT OF PURE METAL FROM THE ELECTROLYTE IS DEPOSITED ON CATHODE. THE SOLUBLE IMPURITIES GO. INTO THE SOLUTION, WHEREAS THE INSOLUBLE IMPURITIES SETTLE DOWN AT THE BOTTOM OF THE ANODE AND ARE KNOWN AS ANODE MUD.
Electrolyte:- A solution of metal salt is used as an Electrolyte.
