DMS, also known as dense or heavy media separation is a physical beneficiation technique by which particles are separated based on difference in specific gravity (SG) (Marion et al., 2017). DMS is commonly applied as a preconcentration step for minerals (such as cassiterite), and in the separation of coal and other economic …
