Project Background

After the tailings slurry produced by the supporting concentrator of the mine settles naturally through the tailings pond, part of the upper clear water will be returned to the concentrator for recycling and part will be discharged. As the mine is adjacent to Ganjiangyuan Nature Reserve and Doushui Lake water source, the drainage water quality outside the concentrator must meet the discharge standard (GB25466-2010) of lead and zinc pollutants before being discharged. The tailings wastewater of lead and zinc mine has large water volume, complex composition and difficult to treat, the clear water on the tailings slurry after natural settlement has problems such as high suspended solids concentration, some heavy metals exceeding the standard and high pH value, which cannot meet the discharge standard. For the treatment of lead-zinc mine tailings wastewater, it is urgent to seek an efficient and low-cost treatment method.

To achieve the effect

The HDCY integrated multi-effect clarification system is greatly simplified compared to the traditional process, and the whole system has the characteristics of one high, one large and two low prices:

(1) High equipment integration, a variety of water treatment technologies are highly integrated in the modular skid-mounted mechanism, suspended solids, heavy metals, fluorine, PH value adjustment and other pollutants and water quality adjustment tasks can be completed, from 500 tons/day to 20000 tons/day can be selected, the project construction period is only 45-60 days, or even shorter.

(2) The amount of water treated by the monomer equipment is large, and the residence treatment time of mine wastewater in the whole system is only 8 minutes, which is the system technology with the largest treatment capacity per unit volume of equipment in the world.

(3) The investment cost is low. The whole system can be tailored according to the project site conditions. It does not require complicated civil engineering and occupies a very small area, which greatly saves the project investment and construction cost.

(4) Low operating cost, the whole set of equipment combined with our most cost-effective pharmaceutical technology to achieve the lowest operating and processing costs.
