The Sink and Float separation process is part of what is also known as a Heavy Media Separation Process (HMS) and are commercial adaptations of the common laboratory procedure used for separating a mixture of two products having differentials in specific gravity by immersing the sample in a heavy liquid having a gravity intermediate to those of the products to be separated.

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. When
Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as heavy media, water or
Dense Medium Separation (also called Heavy Media Separation) is a well-established density separation process. Dense Medium Separation (DMS) uses the characteristic differences in density of the input material to enact a gravimetric-based separation.
Dense Media Separation Relies on Magnetite Removing unwanted materials and increasing product value is an important job made possible by magnetite. When raw materials are extracted from mines, separating the desired product from unwanted waste materials can be a challenge.
According to the application, a suspension of powdered Ferrosilicon or Magnetite in water is used as fluid heavy media in order to allow the separation. To obtain a heavy media with the specific gravity most suitable for the separation, it is necessary to increase or decrease the concentration of Ferrosilicon or Magnetite dispersed in water.
heavy media. The separation by density occurs in the cyclone, with denser particles reporting to the cyclone underflow and less dense particles reporting to the cyclone overflow. The density of the separation is controlled by adjusting the ratio of water to medium in the suspension. Both floats and sinks products pass over a medium recovery screen.
HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of pre-concentration of minerals mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity.
Ad Rem owns the rights on a patented unique bi-directional dense medium barrel that proved to be the most accurate dense medium separator ever employed in the separation of a variety of materials ranging from vegetables to plastics and non-ferrous metals.
This chapter presents the dense medium separation, which is applied to the pre-concentration of minerals that is the rejection of gangue prior to grinding for final liberation.

The medium density correlates to the required separation density needed to achieve a desired product grade. Feed to a heavy media vessel is injected perpendicular to the elongated width of the vessel; Float material travels across the vessel or is removed by a flight conveyor to one end.
Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink.

DENSE. MEDIUM SEPARATION. DENSE MEDIUM SEPARATION (DMS) It is a physical separation technology which relies on the difference in material densities to separate different materials. The mixed solids are placed in a liquid denser than one and less dense than others. The denser material sinks while the less dense material floats.
Magnetic separators that are used in wet processes for the recovery of magnetite from heavy-media separation plants, as well as iron ore recovery, are also discussed. Wet high intensity magnetic separation is introduced. Recommended capacities, feed rates, and magnetic sizes are given.
Heavy Media Separation (HMS) or Dense Media Separation (DMS) hydrocyclones are designed specifically for cleaning applications. Within the cyclone, weight and gravity separate the lighter material from the heavier material, as the media’s buoyancy effect forces the lighter solids to the hydrocyclone’s centre, where they float upward and out
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

Wet Drums for Heavy Media Duty. Wet drums in heavy media applications provide continuous recovery of magnetite or ferrosilicon. Eriez has set the industry standards in the heavy media industry developing both the design criteria of the magnetic circuit and the benchmark of operation.
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
Model HMDA Wet Drum Separators improve the efficiency and reduce the costs of media recovery in heavy media operations. Obsoleting the old "gauss at two inches" standard for selecting wet drum separators, Eriez engineers base their design and application on two fundamental factors: flux density and flux gradient within the separation area.
