The potential for dense medium separation of mineral fines …

1. Introduction. Dense medium separation (DMS) is a process by which particles are separated based on differences in specific gravity (SG). The process can be controlled with a high degree of precision over a wide range of separating densities and is commonly applied as a pre-concentration step for minerals (such as cassiterite) and in …

Dense Medium Separator (DMS)

Dense medium separation (DMS) is a newer processing technology which grew in popularity during the 1950-1970's as many companies used it to replace inefficient jigging processes for separating coal, iron and other ores. From the conversations I have had with current and potential customers about DMS technology it is obvious that though it is a …

The design and Performance of Dense Medium

1. **Separator Geometry:** The design of DMS separators is influenced by the rheological properties of the dense medium, particularly its viscosity and particle size distribution. The geometry of the separator, including the size and shape of vessels, cones, or cyclones, is tailored to accommodate the flow characteristics of the medium.
