Mineral processing: The ore-concentration method that exploits density differences between ore and gangue is called what? Think of gravity-based separation methods. Choose the correct option.

Q: Mineral processing: The ore-concentration method that exploits density differences between ore and gangue is called what? Think of gravity-based separation methods. Choose the correct option.

Concept When ore and gangue differ in density, gravity separation (also called hydraulic washing, Wilfley table, jigging) can concentrate the ore by washing lighter impurities away. Final Answer Hydraulic washing (gravity separation)
