"sink-and-float", "dense-medium separation", "heavy-medium separation" and "heavy-liquid separation" in response to their variations on the basic principle of dense media separation (usually abbreviated to DMS).* They may include: (a) Separation in a quiet single bath (b) Separation with controlled agitation of the bath

After separation, the dense medium is recovered using screens and magnetic separators, and then it is cleaned and reused. DMS is a powerful and efficient technique due to its high capacity, ability to treat a wide range of particle sizes (from 75 mm down to less than 0.5 mm), and high efficiency in separating different minerals based on density.

Dense Media Separation is a well-known sink-float method and technology used within the coal, iron ore and diamond industries.In the process of Dense Media Separation in diamonds, a powdered ferrosilicon (which is an alloy of iron) is suspended in water to form a very defined pulp density (heavy liquid), close to the density of diamond (3.52 g/cm3).

Also known as Heavy Medium Separation, DMS is a technique first pioneered in the 1950s in coal refineries that relies on varying densities of a desired product. In coal industries, the run of mine coal contains impurities such as rock, shale, and clays that makes the product unmarketable. By infusing water with magnetite, operators can alter ...

Dense medium separator is a static separation equipment, while dense medium oscillating chute and dense medium cyclone are dynamic separation equipment. In static separation equipment, the separation medium moves slowly, and it is a stable fine particle suspension liquid whose density is close to that of the mineral particles subject …

However in the Ad Rem bi-directional design, the medium together with solids is injected over a large separation zone, making it almost impossible to bury floats with sinks. 2. The stability of the medium. A typical dense medium bath is relatively deep, and this makes it difficult for the suspension particles to remain in suspension.
