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

To score well you need to revise well, so go through the revision notes of General Principles and Processes of Isolation of Elements given below.

Practise This Question

In a closed container of constant volume, the pressure of water exhibits an interesting dependence on temperature - 

The point D (273.16 K,0.006 atm) is called the triple point, Tp, of water, where all there phases coexist. What is the observed phase change when the temperature is increased from -100C to +100C, while maintaining a constant pressure of 0.006 atm?
