Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention will be further described:

[0025] figure 1 It shows a tailings dehydration device, which mainly includes a cyclone, a thickener, a vacuum belt filter and a sedimentation tank; the tailings slurry discharged from the beneficiation workshop passes through the cyclone, the thickener, and the vacuum belt filter in sequence to form The dry material is placed in the yard. The water collected in the sedimentation tank is the water released by the cyclone, thickener, and vacuum belt filter; the water containing a small amount of tailings deposited in the sedimentation tank enters the thickener for secondary dehydration treatment. There is also a flocculant adding system between the thickener and the vacuum belt filter, so that the fine particles in the tailings slurry and the flocculant in the solution form flocs and settle quickly. The flocculant is polyacrylic acid or polypropylene Amides. The sediment...

Abstract

The invention relates to a dehydration method and a dehydration device of tailings. The dehydration device mainly comprises a cyclone, a thickener, a vacuum belt filter and a sedimentation basin. A tailing slurry discharged from an ore dressing workshop go through the cyclone, the thickener and the vacuum belt filter in order to form dry materials which are placed in a stock dump. And a flocculating agent adding system is installed between the thickener and the vacuum belt filter. The sedimentation basin is connected to a collection basin used for collecting the clear water overflowing from the sedimentation basin, and then the clear water come into the ore dressing workshop for recycling. With the dehydration method and dehydration device of tailings, risks from dehydration with a tailing dam can be eliminated, so that accidents are effectively avoided. Meanwhile, the device of the invention has low investment, low running cost and high dehydration rate.

Description

technical field [0001] The invention belongs to the field of geology and mines, and in particular relates to a tailings dehydration method and a dehydration device. Background technique [0002] In the field of geology and mining, the main measure currently adopted for the treatment of tailings is to use tailings dams. The tailings slurry enters the tailings dam for sedimentation, and the water and solid particles are gradually separated in the tailings dam. The solid particles settle at the bottom of the tank, and the upper layer is mainly clear water. With the continuous inflow of tailings slurry, clear water overflows and continues to be recycled. The particulate matter gradually settles to the bottom and remains in the tailings dam. Realize continuous operation. Adopting this method to deal with tailings has low cost, but there are great potential safety hazards. Tailings dams are themselves a source of debris flows. With the approach of the domestic tailings dam c...
