Background
Mineral resources are important material basis for human survival and development, and make great contribution to the development of human society and the progress of civilization. However, at the same time, the development and utilization of mineral resources also generate a large amount of abandoned mine lands. Mining and smelting have formed 40 million tons of tailings and are still increasing at a rate of 200 million tons per year. The abandoned mine land not only occupies a large amount of land resources, causes damage to the ecological environment, but also threatens the life safety of human beings, and needs to be properly treated and repaired urgently.
The matrix of the abandoned mine land has the characteristics of poor physical structure, low N, P, K nutrient element and organic matter content, poor water and fertilizer retention capacity, extreme impoverishment or unbalanced nutrients, overhigh heavy metal content and the like. Wherein, a large amount of sulfide barren rocks are left in the pyrite mine wasteland, and the heavy metal and sulfide content are high. Under the condition of open-air stacking, the sulfuric acid ferric solution is easily oxidized to form through weathering and leaching, metal ions such as Cd, Cu, Fe, Pb, Zn and the like are further dissolved out when meeting rainfall, and the mining acid wastewater rich in iron, sulfate radicals and heavy metals is formed. The acidic waste water carries a large amount of heavy metal ions to enter underground water or pollute soil and water around a mining area, which affects the growth of crops and causes serious environmental problems.
At present, the method adopted in the aspect of comprehensive treatment of the abandoned mine land is single, namely the ecological greening function is realized through simple surface soil covering and vegetation planting. However, the covering soil is difficult to neutralize the acidity in the matrix and prevent the pyrite from oxidizing and re-acidifying, and the re-acidification degree of the soil is deteriorated.
