Solution

The correct option is A Smelting
The process of removal of unwanted materials from the ore is known as ore concentration.

Froth floatation, electromagnetic separation, and gravity separation are few of the processes used for ore concentration.

Smelting, however, is a process of heating the ore in order to extract the base metal.

Hence B is the correct answer
