Refining using the liquation method is the most suitable for metals with:
- Low melting point
- High boiling point
- High electrical conductivity
- Less tendency to be soluble in melts than impurities
The Correct Option is A
Solution and Explanation
Refining using the liquation method is the most suitable for metals with a low melting point.
So, the correct option is (A): Low melting point.
