Types of Metallurgy
Pyrometallurgy
- Involves the use of high temperatures.
- Examples of metals that can be extracted through pyrometallurgy include Fe, Zn, and Ni.
- These metals are typically found in the middle of the electrochemical series (ECS).
Hydrometallurgy
- Involves reduction in an aqueous solution.
- Examples of metals that can be extracted through hydrometallurgy include Cu, Ag, and Au.
- These metals are typically found at the lower end of the electrochemical series (ECS).
Electrometallurgy
- Involves the use of electrolysis.
- Examples of metals that can be extracted through electrometallurgy include those in Group I, II, and Al.
- These metals are typically found at the higher end of the electrochemical series (ECS).
