WO2016135750A1
column thickener concept To improve the dewatering efficiency, column thickener concept was conceived. In this type of thickener, aspect ratio is much more in comparison with conventional thickeners. The settling rate of particles will be improved further in case of iron ore tailings by applying the magnetic field at particular height of column thickener.
