The operation of the permanent magnet dewatering tank is mainly to adjust the amount of rising water and the size of the discharge port. In order to get a better sorting index for the dewatering tank, it is especially important to pay attention to the impact of the rising water flow on its work. There are two ways to feed up the rising water: the lower feed water and the upper feed water. No matter which water supply method is used, the slurry in the tank will be stable and will not turn over. The effect of the rising water flow is to flush out the fine-grained gangue and slime contained in the slurry. The force acting on the magnetic ore (magnetic + gravity) should be greater than the impulse of the rising water flow, and the momentum of the rising water flow must be greater than the mechanical force acting on the non-magnetic ore (mainly gravity). Therefore, the size of the rising water flow must be appropriate. When the water rises too much, the magnetic fine particles into the overflow easily, appear inverted flower "black run" phenomenon, the tailings grade increased, large metal loss. If the rising water flow is small, the non-magnetic mineral particles are mixed into the concentrate and are not easily washed out, so that the concentrate grade is lowered.

When the rising water flow is certain, if the discharge port is too large, the concentration of concentrate discharge will be reduced, and the concentrate will be easily mixed with the slime to reduce the quality of the concentrate. Conversely, if the discharge port is too small, the sorting indicator will be deteriorated. In order to achieve stable operation and obtain better sorting indicators, it is necessary to determine the appropriate discharge port and rising water volume according to the nature of the ore and the amount of ore to be mined, so as not to block, not to put and not to turn over.
It should be pointed out that adjusting the amount of rising water in the dewatering tank essentially regulates the thickness of the tailings layer, controls the grade of the tailings, and ensures the recovery rate. The regulation of the discharge port is mainly to control the concentration of ore discharge and ensure the quality of the concentrate.
It can be seen that the operation of the dewatering tank has a very important influence on the sorting index. Therefore, it is necessary to create stable working conditions for the dewatering tank, such as uniform ore, fineness, and the various parts of the dewatering tank are in a normal state.
The permanent magnet dewatering tank often fails: the discharge of the mine is caused by no discharge, the groove surface is turned over, and the water cap is worn or fallen off. When these problems are found, they should be stopped for maintenance.
