Options

  1. AElectrolysis
  2. BZone refining
  3. CVapour phase refining
  4. DThermal reduction

Correct answer

D. Thermal reduction

Step-by-step solution

Ellingham diagram is a graph showing temperature dependence of the stability of compounds. This analysis is used to evaluate the case of Reduction of metal oxides and sulphides. This diagram also used to predict the equilibrium temperature between a metal and its oxide.
