Abstract:

Cyanide-containing wastewater caused by cyanide process method are difficult to degrade,it present a problem to the gold mines that how to safely and effectively dispose these highly toxic wastewater.Based on the comparative analysis on advantages and disadvantages of the customary methods for cyanide containing wastewater treatment,the problems of these customary methods were summed up.Combined with the development at home and abroad nearly ten years,four trends of cyanide-containing wastewater treatment technologies were pointed out,which are mult-methods joint application,new energy efficient methods development,new methods industrialization and reactor development.The results can provide a reference for the treatment of mine drainage.

Key words: gold smelting, cyanide-containing wastewater, treatment process, progress
