Pollution status of heavy metals in China's metallic mining areas and treatment measures concerned

摘要

This paper analyzes the distribution and pollution status of metallic mineral resources in China,elaborates the causes and harms of pollution in mining areas,and clarifies the remediation technologies on heavy metal pollution at home and abroad in a systematic way.Based on this,it offers two ways to reinforce the treatment of heavy metal pollution in mining areas.On the one hand,it is essential to use and manage the tailings in a rational manner and guarantee advanced treatment of mineral water during beneficiation to control the pollution of heavy metals in metallic mining areas from the sources.Technologies like physical chemistry and phytoremediation,on the other hand,can be adopted to restore the polluted soil and water bodies,so as to achieve the recycling of the mining soil.
