The liquid film in a spiral separator undergoes an evolution from unsteady to steady flow with increasing trough length. Understanding the process of the flow field evolution is a prerequisite for revealing the mechanism of particle segregation. ... (SPH) model was proposed to simulate the multiphase flow in a Humphrey spiral separator …
Particles within the middle of the trough surface move with the secondary flow and reach their respective place on the spiral trough. Finally, the concentrated minerals (high density) come to the inner region, and undesired materials (low density) occupy the outer area on the trough surface (Bazin et al., 2014; Richards et al., 2000; Tripathy and …

Even Humphrey spiral concentrator reduced the feed to 35.4 wt%, the recovery rate was very low. When the fine aggregate waste was not recirculated, the recovery rate of zircon was 57.03%, monazite 48.79%, ilmenite 35.76%, and magnetite 26.55%. Nevertheless, recirculation of the middlings increased the concentrate to 36.9% …
Spirals come in three forms of trough profiles (ellipse, cubic parabola and synthetic curves) as illustrated in Fig. 11 (Atasoy and Spottiswood, 1995; Kapur and Meloy, 1998; Kwon et al., 2017; Ye et al., 2018). It was observed that coal tends to move to the peripheral end of the spiral as the feed rate and solid concentration increases.
