Dense Media Separation (DMS), also known as Heavy Media Separation, is a technique used to separate particles based on their density. DMS is commonly used to pre-concentrate lithium ores, iron ore, and diamonds and to "wash" coals.

· Dense media separation is widely used in coal, diamond, chromite, and iron ore industries since its introduction by Dutch Sate Mines (DSM) in 1947. Though used occasionally in other industries, its application in precious and base metals, viz., PGMs, gold, copper, and zinc, is slowly gaining some momentum.
