Processing Methods. Although there are a number of different diamond recovery technologies being utilized worldwide, the two principal types are Rotary Pan plants and Dense Media Separation (DMS). Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery.
Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.

Dense medium separation is the process in which a heavy liquid of an intermediate density is used to separate minerals of different specific gravity. The heavy liquid is typically a suspension of dense powder such as ferrosilicon or magnetite in water. Ferrosilicon is used for high-density applications (medium density: 3200–4200 kg/m3).
The primary advantages of using a dense medium cyclone arise when only a single stage separation is required allowing for a simpler circuit and reduced cost (i.e. the dense medium cyclone is generally less expensive). INDUSTRIAL APPLICATIONS While dense media separation is used extensively in the coal industry and somewhat commonly in
Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation.It is also used in coal preparation to produce a commercially graded end-product, clean coal being separated from the heavier shale or high-ash coal.
Dense Medium Separation. Dense medium separation (DMS), also known as Dense Media Separation, is a process where a suspension of dense powder in water is used to form a type of 'heavier liquid' to separate mineral particles in a sink-float process.Many modern dense media plants use this technology because it is both flexible and allows upgrading of resources thereby increasing …

WHAT IS DENSE MEDIUM SEPARATION?Dense medium separation (or heavy medium separation (HMS),or the sink-and-float process) is applied to the pre-concentrationof minerals, i.e. the rejection of gangue prior to grinding for finalliberation.
Dec 16, 2013· Very fine (atomized) FeSi is mixed with water to create a slurry to achieve a defined pulp density. This happens in a prep-tank with (preferably) automatic density measurement. The pulp density is adjusted to a value (t/m3) that lies between the d...
ii. Gravity and Dense-Medium Separation – Separation based on specific gravity of the valuable mineral relative to the gangue and the carrying medium such as water. In dense-medium separation, the a carrying medium is a mixture of water, magnetite, or ferrosilicon.
Condor Dense Medium Separators provide a simple, cost-efficient way to separate and recover valuable minerals at a coarse particle size, ranging from as fine as 0.5 mm to as coarse as 50-70 mm but typically in the range of 1- 50 mm. Dense medium separation technology is used for a wide range of mineral separations to produce premium concentrate.
In South Africa, dense medium separation accounted for 85% of the coal preparation, due to the very high levels of near-gravity material present in coal mined in this region. In China and Germany, jig washing is the dominant separation process used, again, due to the nature of the coal mined.
Useful as a nonionic density gradient medium. Autoclavable, universal centrifugation medium recommended for isolation of macromolecules, nucleoproteins, cell organelles, and a variety of cell types and viruses. Histopaque ® 1077: Suitable for separation of mononuclear cells from human peripheral blood or bone marrow.
Dense medium separation is also known as heavy medium separation or the sink-and-float process. It has two principal applications: the preconcentration of minerals, that is, the rejection of gangue prior to grinding for final liberation, and in coal preparation to produce a commercially graded end-product, that is, clean coal being separated ...
medium cyclone) separation is the most efficient density separation available. The efficiency of HMC separation, however, decreases significantly for particles less than 0.5 mm. A key feature of HMC plant is to removal the fine particles by wet screening prior to separation process. There is little

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.
The primary advantages of using a dense medium cyclone arise when only a single stage separation is required, it allows for a simpler circuit and reduced cost (i.e. a dense medium cyclone is generally less expensive than the multi-stage DMS separator).
The processes considered in this chapter are variously called "sink-float", "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 …
