Recent developments in beneficiation of fine and ultra ...

2020-12-10  The spiral concentrator applies differential density separation between particles to separate the valuable minerals from the gangue minerals. They have been widely utilized in coal washing plants worldwide to treat material in the particle size range 1 mm–150 μm (other reports show that spirals are capable of treating material down to 45um).

Case study: high capacity spiral J concentrators

2015-4-16  of spiral concentrators (the traditional MG4 spiral concentrator and the high capacity (HC) spiral concentrator) under different feed conditions. In addition, the effect of slimes on the spiral concen-trator performance was also investigated. Slimes rheology was linked to the poor concentrator performance at the higher slimes concentrations.
