Abstract:

The smelting plant of Sanshandao gold mine expanding the scale of production.Gold mud raw materials are complex.These cause the poor effect of smelting wastewater treatment and the content of the Cu,Pb,Zn beyond the drainage standard.To solve these problems,this factory compared the research methods of smelting wastewater treatment,and chooses a targeted,economic and practical process to realize the maximization of benefits.

Key words: Smelting wastewater, Iron reduction, Neutralization and precipitation, Drainage standard, Sanshandao
