The application of hydrocyclone in dry tailings discharge means that the tailings slurry output by the beneficiation process is multi-stage concentrated by the cyclone, and then processed by the dewatering screen to form slag with low water content, solidification, and easy storage. Eliminate the hazards of traditional wet tailings ponds and reduce environmental pollution. The dry tailings occupy a small area and can be reused.

The application of hydrocyclone classifier in tailings discharge

The cyclone mainly plays the role of dehydration and concentration in the process of dry tailings discharge. The tailings enter the hydrocyclone for dehydration and concentration. The underflow directly enters the dewatering screen, and can be directly discharged after being dehydrated by the dewatering screen. The overflow enters the thickener, and the underflow of the thickener enters the filter press for dehydration treatment. The tailings that can be discharged dry are formed, and the overflowing water of the thickener can be recycled.

Other equipment in the dry tailings process

The hydrocyclone + thickener + multi-frequency dewatering screen group is a new generation of tailings dewatering process, which can be suitable for dewatering various ores within -325 mesh and 80%, and the dewatering rate can be as low as 15%. The operating cost of this group of equipment is 50-70% of the equipment of other units, and the equipment is lined with wear-resistant rubber parts, the replacement frequency of loss parts is low, and the service life of the equipment is also extended. Considering comprehensively, the dry tailings discharge process is suitable for small and medium-sized enterprises to invest and use, and it is a cost-saving, efficient and practical tailings dry discharge equipment.

The cyclone has a wide range of applications and plays a vital role in dry tailings discharge operations. It can also be used for grinding and grading, dewatering of tailings, desliming of ore slurry, etc.
