| Abstract: | In this paper the pretreating technique has shown to be a valid approach for direct extraction of gold from complex ores through pilot-test with the scale of 1.5 tone per batch in Dongtongyu Gold Mine. It is characterized by high leaching index, simple flowsheet and low cost. The essence of pretreating reagents, grinding degree and the control of cyanidization. 2figs., 4tabs., 2refs. |
