Study Notes
Ores of Metals
- Haematite (Fe2O3) is an oxide ore.
- Zincite (ZnO) is an oxide ore.
- Cassiterite or Tin stone (SnO2) is an oxide ore.
- Iron Pyrite (FeS2) is a sulphide ore.
- Galena (PbS) is a sulphide ore.
- Copper Pyrite (CuFeS2) is a sulphide ore.
- Calamine (ZnCO3) is a carbonate ore.
- Siderite (FeCO3) is a carbonate ore.
- Malachite (CuCO2.Cu(OH)2) is a carbonate ore.
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).
