Refining using liquation method is the most suitable for metals with

Options

  1. ALow melting point
  2. BHigh boiling point
  3. CHigh electrical conductivity
  4. DLess tendency to be soluble in melts than impurities

Correct answer

A. Low melting point

Step-by-step solution

This process is used for refining easily fusible metals like lead and tin. The impure metal is heated on the sloped hearth of a reverberatory furnace. The metal melts and flows down leaving the impurities. Liquation is a metallurgical method for separating metals from an ore or alloy. The material must be heated until one of the metals starts to melt and drain away from the other and can be collected. This method was largely used to remove lead containing silver from copper, but it can also be used to remove antimo
