Thus, there was an urgent need to develop a novel method for adjusting the second-stage separation density of a dense medium cyclone. In recent years, magnetic devices had been widely applied because of their functional diversification (Ali-Zade et␣al., 2008; Augusto et␣al., 2004; Premaratne and Rowson, 2003; Sripriya et␣al., 2003), and …

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 …

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.
