Abstract

Taking the disposal of huge-scale tailing slag generated in the construction of a fluorite lead-zinc mine in Chenzhou, Hunan province and greening of the dump as the research object, the physical and chemical defects of tailing slag were clarified by soil obstacle factor identification firstly. Then, biochemical fulvic acid (BFA), ammonium dihydrogen phosphate, zeolite and organic fertilizer were used to modify the corresponding properties. After that, a modified tailing matrix was used as the planting soil. Furthermore, a pot experiment in an artificial climate incubator combined with a pilot test in mine was used to evaluate the remediation effect of modifier and plant on tailing slag, and an ecological restoration method based on in-situ matrix improvement and direct vegetation of tailing was proposed eventually. The results showed that when the addition amount of BFA, ammonium dihydragen phosphace, zeolite and organic fertilizer was 0.5%, 0.4%, 2% and 15% respectively, the pH value and dry density of tailings decreased by 25.8% and 77.6% respectively, and non-capillary porosity, organic matter content, hydrolytic nitrogen content and available phosphorus content of tailings improved by 1.49 times, 26.7 times, 9.3 times and 20.9 times, respectively. The results of pot experiment and field pilot test showed that the comprehensive enrichment and transport ability of Eleusine indica to fluoride, lead and zinc, was the highest; Cosmos bipinnata had the best comprehensive accumulation capacity, and the enrichment amounts of lead, zinc and fluorine were 267.2 mg/kg, 432.8 mg/kg and 513.2 mg/kg, respectively; Amaranthus hybridus was the selected plant with the transport coefficients of lead, zinc and fluorine of 0.485, 1.208 and 1.810, respectively. In order to achieve the reclamation effect of fluorite lead-zinc mine, it is necessary to plant Eleusine indica, Cosmos bipinnata and Amaranthus hybridus simultaneously.
