Question

Gravity separation is based on the difference in the __________ of the ore and the gangue particles.

• A. solubility
• B. magnetic properties
• C. density

Answer 1

The correct option is C density

Gravity separation is a method that concentrates the ore by passing it through an upward stream of water.
This method is used for ores that contain comparatively heavier metals.
Therefore, the gravity separation technique is based on the difference in densities of ore and gangue particles.
