Shaoguan Pb-Zn smelter (Imperial Smelting Process)
Shaoguan, northern Guangdong (Beijiang River), China
Mine tailings and waste rock
- Type
- Mine tailings and waste rock
Large Pb-Zn smelter (ISP) upstream on the Beijiang, historical source of thallium pollution. Light thallium goes into the vapour phase (about -3.75 ε units) then settles on dusts and sludges, the slag remaining heavy. Indicative coordinates: Shaoguan city.
