Dense-Heavy Medium Separation HMS / DMS Process

Dense-Heavy Medium Separation HMS / DMS Process. Since most of the liquids used in the laboratory are expensive or toxic, the dense medium used in industrial separations is a thick suspension, or pulp, of some heavy solid in water, which behaves as a heavy liquid. The process offers some advantages over other gravity processes.

Dense Media Separation | SpringerLink

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 DMS).* They may include: (h) Centrifugal aid, e.g. by cyclone bath.

The stability of ferrosilicon dense medium suspensions

General background. 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.

Media, Medium, and Mediums: How to Choose the Right Word

"Media" may refer either to ple communication outlets or to a single such outlet. At the same time, however, "media" is the plural of "medium." Thus, "The media is having a field day," is correct—but so is "I work in several media, including clay and fiber."

Densification and Dense Medium Control Strategies The control of the medium density is a major factor in the operation of the dense medium separation process. The medium density must be kept in close tolerance to the target or set-point density to avoid displacement of near density material which will affect the yields and product grades.

The dense medium slurry, made up of a suspension of ferrosilicon or magnetite in water, is introduced through the media inlets at the bottom end of the separator countercurrent to the ore feed. The densest ore particles are separated and transferred through the sinks outlets, while the less dense material is transferred to the second stage of separation where more sinks material can be recovered.
