The proper inflow of medium can be estimated to be 260 gallons/min for every foot of overflow weir length. For example, a 15 ft weir length vessel would require a dense medium flow rate of 15 ft x 260 gpm/ft = 3900 gallons/min To check for proper flow, one can physically measure the fluid depth overflowing the weir. The proper depth is 3 ¾-in.

 · Dense medium separation (DMS) is often used to reject a large portion of gangue material upfront to create cost and energy savings during processing. As lower-grade ores with complex mineralogy are being increasingly exploited, the properties of the gangue minerals begin to play a more important role in the upgrading of the ore.

The primary processes are crushing and grinding of ore, ore sizing and separation. To separate the ore into applicable sizes for further processing, screening, classifying, concentration separation, heavy medium separation, gravity and/or magnetic separation, and flotation applications are used.

 · The Sink and Float separation process is part of what is also known as a Heavy Media Separation Process and are commercial …

 · 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 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).
