Abstract：
In order to provide some method reference for further reducing medium consumption, the necessity of reducing medium consumption from the perspective of economic benefits was demonstrated, the methods of reducing medium consumption from the aspects of management and technology were discussed. It is discussed from three aspects: from the perspective of economic benefits, the medium has a great impact on coal ash, and reducing medium consumption can increase economic benefits; The maintenance management is in place to ensure the normal operation of the equipment and the protection of the equipment from misoperation, which can reduce the medium consumption; Maximizing the recovery of qualified suspension, intercepting medium and recovering medium are the main technical means to reduce medium consumption. Maximizing the recovery of qualified medium can reduce the product medium and reduce the feeding amount of magnetic separator. Maximizing the intercepting medium can reduce the product medium and maximize the recovery medium to reduce the tailings loss of magnetic separator medium.
Key Words： medium loss;heavy medium;management
