Technical Field
The invention belongs to the technical field of rare earth protection, and particularly relates to an ecological restoration device for a rare earth mining area and a using method thereof.
Background
The exploitation and extraction of rare earth cause great damage to the environment. Since the discovery in the early 70 s of the last century, a new rare earth resource development industry has rapidly emerged. The mining of the mine is sequentially subjected to three different process technologies of pond leaching, heap leaching and in-situ leaching. The heap leaching process generally adopts large-scale mechanical excavation and shipping, the earth surface vegetation is greatly damaged, the heap leached tailings are directly left in a yard, and some enterprises build a dam again on the original heap leached tailings for heap leaching and recycle. If the dam body is poor in quality, the dam can be broken, and the ecological environment is damaged more greatly by a large amount of discharged tailings than by a pool immersion process. The in-situ leaching method abandons the method of directly destroying water and soil by a heap leaching process, and can reduce the damage degree to vegetation. Apparently, the water loss and soil erosion are reduced, but landslides and even collapse are easily caused with the lapse of time. And the injected ammonium sulfate solution in the in-situ leaching method cannot be fully and effectively recovered, and the ammonium sulfate solution which is not recovered permeates farmlands and water sources to cause pollution of soil and water sources, so that the method is an important topic for ecological recovery of rare earth mining areas.
However, when the rare earth mining area is subjected to ecological restoration, the soil fertility is not high due to soil desertification, the water storage effect is poor, and plants are difficult to plant.
