advantages of dense medium separation process
Dense Media Separation | SpringerLink
The processes considered in this chapter are variously called "sinkfloat", "sinkandfloat", "densemedium separation", "heavymedium separation" and "heavyliquid separation" in response to their variations on the basic principle of dense media separation (usually abbreviated to DMS).*

dense media separation process
Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse asmm and as fine as#;m with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrousbased media recovery. Read More >>

Description of Absorption. Another separation process used in industry is absorption, which is used to remove a solute from a gas stream. It accomplishes this by contacting the gas mixture with a liquid solvent that readily absorbs the undesirable components from the gas stream, purifying the gas stream.
