Dense media separation is also known as what?

• A. Magnetic separation
• B. Crushing separation
• C. Heavy media separation
• D. Light media separation

Answer: (C)

Dense media separation is a density-based gravity separation method that uses a dense liquid as the floating medium to split particles by their specific gravity. The medium’s density is chosen between the densities of the two materials being separated, so the heavier particles sink while the lighter ones float. This is why the technique is commonly called heavy media separation—the emphasis is on using a heavy, dense medium to achieve the separation. Magnetic separation, by contrast, relies on magnetic properties rather than density. The term “crushing separation” isn’t a standard method, and “light media separation” isn’t how this density-driven process is described.
