The concentration of cassiterite ore is carried out by which of the following methods?
- Adsorption phenomenon
- Froth floatation
- Electromagnetic separation
- Liquification
Correct answer: Electromagnetic separation
Solution
Cassiterite (SnO2) is concentrated by electromagnetic separation because the ore particles respond differently to a magnetic field compared to the gangue. Froth flotation is used for sulfide ores, not oxide ores like cassiterite.
