The process of removing lighter gangue particles by washing in a current of water is called:
1 Levigation
2 Liquation
3 Leaching
4 Cupellation
Explanation:
Lighter gangue particles are washed in a current of water by a process called levigation. In levigation, the powdered ore is agitated with water or washed with an upward stream of running water, the lighter particles of sand, clay, etc., are washed away leaving behind heavier ore particles.
