Since the classification in a spiral concentrator depends on particle specific gravity and size, the operation of spirals can be analyzed using size recovery or partition curves (Bazin et al., 2014). Spiral concentrators possess multiple design parameters for a variety of applications. The design parameters that govern the performance of the ...

The beneficiation of iron ore slimes by selective flocculation was studied. Polyacrylamide (PAM) and guar gum were used as flocculant, along with sodium hexametaphosphate (SHMP) as a dispersant.

magnetite and quartz particles in the presence and absence of magnetic field was investigated via analyzing variations in the forces that affect particles' separation in a spiral. Changes in Zero force line were considered as the reference point in the studies. In this regard an innovative magnetic-spiral was designed and fabricated.
