In order to study the influences of ultrasonic frequency, power and application time on the underflow mass concentration of unclassified tailings discharge, ultrasonic technology was introduced to explore the effect of ultrasonic coupled with mud layer on the underflow mass concentration and sand discharge of thickener. Firstly, the directivity of ultrasonic in unclassified tailings slurry was analyzed by MATLAB software, and the optimal frequency range of ultrasonic wave was selected. Then, the optimal frequency of ultrasonic was further determined by interpolation fitting method. Finally, the optimal frequency, power and application time of ultrasonic were calculated through the interaction of factors, and verified by support vector regression model. The results show that when the ultrasonic frequency is 28 kHz, the propagation directivity in the thickener is better. Under suitable ultrasonic conditions, ultrasonic has a significant effect on increasing the final mass concentration of unclassified tailings slurry. The optimal operating conditions of the ultrasonic for flocculation settlement of the unclassified tailings are as follows: after the natural settlement of the unclassified tailings for 1 min, the ultrasonic frequency is 28 kHz, and the ultrasonic power is 100 W.
