1. reasonable structure and small occupation area high recovery high efficiency precious separation light in weight rush and corrosion resistant. 2.Spiral chute is to make seperations of useful minerals from gangues by use of the different particles to gravity hydraulic pressure and friction in the multi-force field through dynamic centrifugal flowing membrane of slurry produced on the inclined surface of spiral based on the differences of useful mineral and gangue in specific gravity, particle size and shape.
