Study on the Remediation of Tailings by Modified Biochar
mine environment restoration is one of the specific measures to build a"beautiful China"and implement the"two mountains"policy.Remediation of water pollution caused by tailings is also an important part of many mine environmental problems.In this paper,the sampling study around Xiangtan Manganese Mine shows that the highest concentration of heavy metals around the tailings is Mn,followed by Cd,Zn,Pb,etc;Mn pollution is serious in some areas,and Cd and Cr pollution is a potential threat.This study is devoted to analyzing pollutants and using biochar or modified biochar to repair tailings.
