The Tibet 1,500tpd lead-zinc mine project is a tailings dry discharge project undertaken by Xinhai Mining. The tailings processing capacity of this project is 1,500t/d, and the average tailings concentration is 28%. The tailings dry discharge process designed by Xinhai is a dehydration process of hydrocyclone + dewatering screen + filter press. The final tailings moisture content is less than 20%.

The upper part of the dehydration screen is transported out of the workshop by a belt for storage, and the lower part of the screen is transported to the concentrator by a pump.
The overflow of the cyclone flows to the concentrator. After concentration, it is pumped into the filter press with the filter press feeding pump and pressed into a filter cake. It is transported out of the workshop with a belt and stored outside the workshop. The filter press filtrate The filtrate flows from the dewatering screen to the filtrate buffer tank, and then is transported to the concentrator by a pump. The overflow of the concentrator flows to the return tank. After clarification, it is transported back to the dressing plant by a return pump for use.
The concentration of the tailings after treatment is 80%, the water recovery rate is 92%, and the water content of the tailings after treatment is less than 20%.
