Abstract: Based on analyzing the composition of the reclaimed water of the tailings pond,taking a wet tailings pond in Xilingol League in Inner Mongolia as an example,a method of increasing the reclaimed water by using suspended ball is proposed.Theoretical analysis and comparative test  verification results show that the method can greatly reduce the evaporation and increase the reclaimed water,it is worth popularizing in the management of tailings pond in the water shortage area.

Key words: Tailings pond, Reclaimed water, Evaporation, Suspended ball
