Which one of the following statements is not correct?

Options

  1. Avan-Arkel is method is used for refining of zinconium
  2. BMond process is used for refining of nickel
  3. CZone refining is based on the principle that the impurities are more soluble in the melt than in the solid sta
  4. DHigh melting metal are refined by liquation

Correct answer

D. High melting metal are refined by liquation

Step-by-step solution

Liquation method is used for refining of such impure metals that are readily fusible (having low melting points) such as Pb , Sn , Bi and Hg as compared to impurities (less fusible). The other queen statements are correct. Hence, option (d) is incorrect.
