Study on Recovering Copper by Electrowinning Method from Concentrated Effluent Containing Cyanide Solution

The research results of recovering copper by electrowinning from concentrated cyanide solution were described.A series of experiments were made about electrode material,electric current,free cyanide ions,electrowinning time,temperature and electrode distance.The best condition was investigated in electrowinning process.Copper-electrowinning content reached over 99% or more.The experiments provide reliable process parameters for industrialization.
