Dense media separation is also known as what?

• A. Dense media separation
• B. Water separation
• C. Air separation
• D. Heavy media separation

Answer: (D)

Dense media separation relies on a dense, suspended medium to sort minerals by density. This medium is a heavy slurry (often magnetite-based) whose density is tuned so that particles with higher density sink and lighter ones float. Because the process centers on using a heavy, dense medium to achieve the separation, it’s commonly called heavy media separation. The two terms describe the same technique, just with different emphasis on the medium’s heaviness vs. its density. Water separation would use water as the separating medium and relies on simple settling, while air separation uses airflow, so they don’t fit this method.
