Question
Which one of the following is not a method of concentration of ore?
- Gravity separation
- Froth floatation
- Electro-magnetic separation
- Smelting
Hint:
concentration of ore.
The correct answer is: Smelting
Smelting is the process of producing metals from their ores, for example copper and zinc. L. Lu, ... D. Zhu, in Iron Ore, 2015 Smelting is a form of extractive metallurgy to produce a metal from its ore.
