Review of ecological restoration technology for mine tailings in China

Abstract

The disposal of mine tailings is identified as one source of an environmental impact finally resulting in a typically degraded ecosystem. It can easily cause air and water pollution and is a source of man-made mudslides with high-potential socio-economic-energy impacts. Pollution control and ecological restoration technologies of mine tailings have become the burning question in China. In this paper restoration technologies for mine tailings in China are reviewed, by pointing out problems and deficiencies of physical remediation, chemical remediation, bioremediation and phytoremediation. On this basis, the existing problem and the future development of ecological restoration technology for mine tailings in China were discussed and some suggestions proposed. The utilization of comprehensive restoration technologies is a trend for future development. Management systems should be improved in order to promote the sustainable development of mining in China.
