Which among the following elements is obtained in pure form by liquation process of refining?
- A Copper
- B Tin
- C Gallium
- D Silicon
Answer & Solution
Correct Answer
(B) Tin
Step-by-step Solution
Detailed explanation
Liquation is used for the refining of metals having low melting point and are associated with high melting impurities. For example, Pb, Sn, Sb, Bi and Hg. The impure metal is heated on the sloping hearth of a furnace. The pure metal flows down leaving behind the non-fusible material on the hearth.
