  • An improved dewatering process for mill tailings

    The mill tailing, after pulp density adjustment, is fed to the hydrocyclone which yields two products. The underflow product is sent to the settling cone for further dewatering. The overflow product, together with the settling cone overflow, goes to the thickener which, with the aid offlocculants, gives a clear effluent and a relatively dilute underflow. The latter combines with .
