Removal of metals from lead-zinc mine tailings using

2017-10-1  Lead-zinc tailings used for this study were collected from a lead-zinc mine plant in Shaoguan, China. Lead-zinc mine tailings were prepared by crushing and screening the material to particle sizes below 74 μm. A representative sample of the mine tailings was pulverized to conduct the chemical and mineralogical analysis.
