  • Column thickener and a process thereof for dewatering of iron ore slurry
    Patent number: 10370271
    Abstract: The present invention is related to a high aspect ratio column thickener and a process thereof useful for dewatering of iron ore tailings. The column thickener has been developed with multiple feed inlet points and an auxiliary inlet point for water to clear the jam of high concentration slurry, if required. The column also consists of a conical portion at the bottom. Magnetic field has been applied using induced magnetic coil just above the conical portion of column thickener. Iron ore tailings slurry is fed into the column thickener and particles are allowed to settle in axial direction with and without the application of magnetic field.
