process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth’s crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and earthly substances called Gangue. The extraction of metals and its isolation occurs over few major steps:
Concentration of Ore
Isolation of metal from the concentrated Ore
Purification of the metal
Concentration of Ore
Isolation of metal from the concentrated Ore
Purification of the metal

✔️ 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.
