Problems solved by technology

The existence of these elements has a great relationship with plant growth. When these heavy metal elements exist in a small amount, they can be used as nutrients in the soil to promote plant production; but when these elements exist in excess, they become toxic substances for plants. Unfavorable growth, especially when a variety of excessive metal elements are present in excessive amounts, due to the synergistic effect of toxicity, their growth hazards to plants are significantly increased
[0006] 2. Strong acidity and alkalinity and large changes
[0008] 4. The surface of solid waste is unstable
Especially after the tailings are eroded, there will be erosion grooves and cracks on the surface, which will cause the topsoil covering the tailings and waste rocks to be broken. Due to the action of gravity, the topsoil may wriggle. Therefore, the stability of the topsoil very low
The instability and mobility of the topsoil will seriously damage the normal growth of plants.

Embodiment 1

[0046] Embodiment 1: This embodiment provides a method for ecological restoration of tailings ponds for lead-zinc tailings ponds, including the following steps:

[0047] S1: Close the tailings pond and measure the size of the tailings pond.

[0048] S2: Drain the water in the reservoir; preferably, introduce the water in the reservoir into the labyrinth sedimentation tank, after the water in the reservoir is settled in the labyrinth sedimentation tank, the supernatant is pumped out through the lifting pump for production recycling; the sediment is cleaned regularly discharge.

[0049] S3: Naturally air-dried tailings storage.

[0050] S4: level the tailings 1, and add a stabilizer to the tailings 1; preferably, use a scraper to remediate the tailings 1, and after leveling the tailings 1, add a stabilizer to the tailings 1 for acid-base neutralization deal with. For the lead-zinc tailings pool in this embodiment, the pH value of the lead-zinc tailings is generally about 5.05...

Abstract

The invention discloses an ecological restoration method of a tailings reservoir. The method comprises the steps as follows: S1: closing the tailings reservoir and measuring the size of the tailings reservoir; S2: pumping dry water in the reservoir; S3: air drying the tailings reservoir; S4: leveling the tailings reservoir, and adding a stabilizer to the tailings reservoir for neutralization; S5: filling the tailings reservoir with soil and performing rotary tillage; S6: planting crops. The ecological restoration method of the tailings reservoir can reduce the influence of structural characteristics of tailings on the crops, restores the ecological environment of the abandoned tailings reservoir, and returns the field to agriculture.

Description

technical field [0001] The invention relates to the technical field of ecological restoration of abandoned mining areas, in particular to a method for ecological restoration of tailing ponds. Background technique [0002] With the development of the economy, the demand for mineral products has increased significantly, the scale of mining development has increased accordingly, and the amount of tailings produced has also continued to increase. In addition, the grades of many available metal ores and chemical non-metallic ores are decreasing day by day. In order to meet the growing demand for mineral products, the scale of beneficiation is getting larger and larger, and the number of beneficiation tailings produced is also greatly increasing. At present, except for a small amount of tailings being utilized, such as paving roads, quite a lot of tailings can only be piled up, occupying a large amount of land, and with the increase in the number of tailings, and the low utilizati...
