Note down the general metallurgical processes.
Metallurgy is the branch of science that deals with the extraction of metals from their ores and refining them.
Following are the general processes involved in metallurgy:
• Crushing and Pulverization
• Concentration of Ore
- Hand-picking
- Gravity separation
- Froth floatation
- Magnetic separation
- Leaching
• Calcination / Roasting
• Reduction of Ore into free Metals
- Carbon reduction
- Alumino thermite reaction
- Self reduction
- Electrolytic reduction
• Refining of Metal
- Liquation
- Poling
- Electrolytic...
