Which one of the following statements is not correct?
- A van-Arkel is method is used for refining of zinconium
- B Mond process is used for refining of nickel
- C Zone refining is based on the principle that the impurities are more soluble in the melt than in the solid state of the metal
- D High melting metal are refined by liquation
Answer & Solution
Correct Answer
(D) High melting metal are refined by liquation
Step-by-step Solution
Detailed explanation
Liquation method is used for refining of such impure metals that are readily fusible (having low melting points) such as \(\mathrm{Pb}, \mathrm{Sn}, \mathrm{Bi}\) and \(\mathrm{Hg}\) as compared to impurities (less fusible). The other queen statements are correct. Hence, option…
