Enlist the various steps involved in the extraction of metals.

(N/A) The extraction of metals from their ores involves three major steps:
$1$. Concentration of Ore: This process removes gangue (impurities) from the ore. Methods include:
- Hydraulic Washing
- Magnetic Separation
- Froth Flotation
- Leaching
$2$. Isolation of Metals from Concentrated Ore: This involves converting the concentrated ore into crude metal. Methods include:
- Calcination
- Roasting
- Smelting
- Electrolytic Reduction
- Auto-Reduction
- Thermite Reduction
$3$. Refining of Metals: This process purifies the crude metal to obtain pure metal. Methods include:
- Distillation
- Liquation
- Vapour Phase Refining
- Zone Refining
- Poling
- Chromatography
- Electrolytic Refining
- Cupellation
