Tailings dry stacking technology in mining

There is many tailings dry stacking process. In order to solve the problem of tailings dehydration, the concentration (concentrator or cyclone) + filter or filter press system was commonly used in the past, but there is a large area, large investment, high power consumption, and use cost Higher issues.

In recent years, a new tailings treatment process that has gradually emerged in China refers to the concentration of the tailings slurry output by the beneficiation process, and then processed by the dehydration vibrating screen equipment. The water content of the product on the screen is usually below 20% and can be directly transferred Go to a fixed location for dry storage.

This process has the advantages of small investment, high efficiency, small footprint, low operating cost, etc. It is currently widely used in the market. If used in conjunction with a filter or filter press, the area of the filter and filter can be greatly reduced. Due to the significant advantages of this process, it was quickly promoted and applied in China.

GP series tailings dry discharge sieve is a vibrating screen specially developed for metal tailings dry discharge based on GZ series high frequency sieve combined with the characteristics of metal tailings, mainly used in iron ore, copper ore, gold Mine, aluminum ore tailings are dehydrated. It is a new type of high-quality tailings recovery equipment designed for the problems of a large number of tailings dry discharge screens in China after sufficient demonstration and research. It has simple structure, low cost, high efficiency, low energy consumption, low noise and easy maintenance Features.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

Several types of flocculation tanks

The concentrator is a continuous working concentration and clarification equipment. It is mainly used for dehydration of fine and tailings pulp in wet beneficiation operations. It is also widely used in the concentration of solid slurry in coal, steel, chemical, building materials, water sources and sewage treatment. And purification. The ordinary concentrator works reliably, has low operating costs, and can store and buffer the feedstock. However, it is based on the gravity sedimentation of the particles. The sedimentation velocity is proportional to the square of the particle diameter, which is used to treat the microparticles and has low efficiency. The high-efficiency concentrating machine mainly uses the reasonable use of flocculant and the cloth feeding method at the bottom to increase the sedimentation speed, which is one of the most important progress in the concentration technology. Different type of flocculation tanks Thickener tanks , Deep Cone Thickener, Sludge Thi...

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
