Experimental study on comprehensive treatment of acid mine drainage in a mine
In response to the environmental pollution risks posed by acid mine drainage surrounding a non-ferrous metal mine,experimental study was conducted on the removal of iron,copper recovery by sulfurization and neutraliza-tion treatment.The results indicate that after the process of mixed iron removal and copper recovery-neutralization treatment,the pollutants in the acid mine drainage met the requirements of Grade I of the GB 8979-1996"Compre-hensive Wastewater Discharge Standard".The produced neutralization residue exhibit leach toxicity levels that meet the general industrial solid waste requirements.The copper grade in the copper residue can reach over 35%,and the comprehensive copper recovery rate can reach 93.9%.
