Question

Gravity separation, also known as hydraulic washing, is a preliminary beneficiation technique frequently used for oxide ores. This method physically separates particles based primarily on which difference between the ore and the gangue?

Prashant Kotian · Accepted Answer

Correct answer: B. Gravity separation relies on the difference in specific gravities (densities) of the heavy metallic ore particles and the lighter earthy gangue particles. Water streams wash away the lighter gangue.
