Thiourea–thiocyanate leaching system for gold
Hydrometallurgy, 2011 The leaching of gold in thiourea-thiocyanate solutions has been studied by the rotating-disc technique using ferric sulfate as oxidant. The effects of initial concentrations of ferric, thiourea (Tu) and thiocyanate as well as temperature and pH on gold ...

Response of low-grade gold ore to cyanidation and thiourea leaching
Particulate Science and Technology, 2019ABSTRACTIn this study, leaching tests were conducted on representative samples provided from Hamze-Qarnein gold deposit with grade of 0.8 ppm using cyanidation and thiourea leaching. Effective parameters including particle size, reagent concentration, oxidant concentration, pH, and dissolution time were examined in both cyanidation and acidic ...
