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 socioeconomic-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.
