How does gold's high specific gravity influence gravity concentration methods?

How does gold's high specific gravity influence gravity concentration methods?

• A. It prevents gold from separating from other minerals in gravity circuits.
• B. It makes gold behave similarly to lighter minerals in most gravity devices.
• C. It has a specific gravity of about 19.3, which allows gold to separate from lighter gangue minerals in gravity circuits.
• D. It requires chemical leaching to recover gold rather than gravity separation.

Answer: (C)
