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 Separation (DMS)
The paper discusses various aspects of the application of heavy-medium separation to the processing of hematite ore at Sishen and Thabazimbi. The two main factors to be borne in mind in the design of a plant for such beneficiation are the Iow unit value of the iron ore produced and the high separation densities required. The four factors of ...

DENSE MEDIUM SEPARATION USING A MAGNETIC …
The application of a magnetic field around a DMS cyclone influences the medium stability (Svoboda et al, 1998). If the medium is unstable, it would influence the separation within a DMS cyclone and consequently render the process inefficient and costly (Myburgh, 2001). Due to an increased stability of the medium with the
