Inner Mongolia 3000t/d lead-zinc mine tailings dry discharge project

Tailings dry discharge plan

Use a pump to pump the tailings slurry into the /strong>, the objects above the screen are coarse-grained dry tailings, which are transported by belt conveyors to the tailings storage site for storage; the overflow of the cyclone group enters the peripheral rack drive concentrator for concentration, The underflow of the thickener is pumped into the filter press by a slurry pump for pressure filtration. The filter cake is fine-grained dry tailings, which is transported by a belt conveyor to the tailings storage site for storage.

(dehydration screen dehydration process)

(Concentrator during concentration and dehydration operation)

Ore processing Factory water return plan

The water under the screen is pumped into the concentrator; the filtrate and the overflow of the concentrator can flow into the return pool and return to production for use.

Project results

The tailings dry discharge process designed by Xinhai Mining for this tailings dressing plant has a unique equipment combination, simple process, and good dry discharge effect. The final tailings discharge is dry The water content of the mineral is as low as less than 15%. In addition, the equipment used in the tailings dry discharge process is lined with Xinhai wear-resistant rubber, with a wear-resistant index of up to 128%. The life of the entire production line is twice that of an ordinary equipment production line, greatly reducing manual maintenance and operating costs by at least 2 yuan. /ton or more.
