Chemistry Revision Notes for Class 12 Chapter 6 General Principles and Processes of Isolation of Elements

CBSE Class 12 Chemistry Revision Notes for General Principles and Processes of Isolation of Elements is discussed here. Metallurgy is the technological and scientific process which is used to isolate metal from its ore. Three steps involved in the metal extraction process are Concentration of Ore, Isolation of metal from concentrated Ore, and Purification of the metal. The following steps help to isolate crude metal from extracted ore.

Step 1: Conversion to oxides

  • Calcination
  • Roasting

Step 2: Reduction of oxides to metals

  • Smelting
  • Reduction by hydrogen
  • Reduction by aluminium
  • Auto reduction
  • Reduction by Mg
  • Electrometallurgy
