Extraction of Gold from Refractory Gold Ore in Dongbeizhai By Electrochemistry-Cyanide Leaching Method

To seek ways of exploiting and utilizing the large scale gold deposit in Dongbeizhai,Sichuan,a novel method,i.e.,extraction of gold by way of electrochemistry cyanide leaching,is put forward. Based on the study of the method priciples and comparision with other methods, the method described in this paper indicates that the rate of leaching gold was higher than others, and the period of leaching gold was shortened.
