Heavy-media separation Britannica

Other articles where Heavy-media separation is discussed: mineral processing: Gravity separation: In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon). Such a suspension can simulate a fluid with a higher density than water.
