Reduction of Thiourea Consumption in Gold

1997-7-2  The thiourea leaching of gold and silver from the gold-bearing silicate ore of the Hishikari mine (Kagoshima, Japan) was studied. The apparent activation energy of the extraction of gold and silver was smaller than that of the reaction rate of thiourea consumption by ferric iron. We carried out the leaching after the leaching solution was preserved for several hours. The gold recovery at 288 K ...
