Introduction. Dense medium separation (DMS) is a process by which particles are separated based on differences in specific gravity (SG). The process can be controlled with a high degree of precision over a wide range of separating densities and is commonly applied as a pre-concentration step for minerals (such as cassiterite) and in …
