Question

Identify the process of refining to obtain pig tin.

Options

• Polling

• van Arkel

• Liquation

• Mond process

Answer 1

Liquation

Explanation:

Pig tin is obtained using the liquation process, which is a partial melting technique for separating elements of an ore, metal, or alloy. The liquid constituent can be drained off when the material is heated to a temperature where one of the constituents melts and the other stays solid. The non-fusible substance on the health is left behind when the pure metal (tin) flows down.
